group policy

To instruct IGMP / MLD snooping to use the specified route policy to determine the weight contributed by a new <*,G> or <S,G> membership request, use the group policy command in the appropriate snooping profile configuration mode. To remove the group weight route policy from the profile and use the default group weight of 1 for all groups, use the no form of this command.

group policy policy-name

no group policy

Syntax Description

policy-name

Name of the route policy that should determine the weight contributed by a new <*,G> or <S,G> membership request.

Command Default

Default weight for all groups is 1. By default, no route policy is configured to determine the weight of new <*,G> or <S,G> membership requests.

Command Modes

IGMP snooping profile configuration

MLD snooping profile configuration

Command History

Release

Modification

Release 3.9.0

This command was introduced.

Usage Guidelines

To limit the number of IGMP v2/v3 groups, in which the maximum number of concurrently allowed multicast channels must be configurable on a per EFP-basis and per PW-basis, configure group weighting.

IGMP snooping limits the membership on a bridge port to a configured maximum limit. This feature also supports IGMPv3 source groups and allows different weights to be assigned to individual groups or source groups. This enables the IPTV provider, for example, to associate standard and high- definition IPTV streams, as appropriate, to specific subscribers.

This feature does not limit the actual multicast bandwidth that may be transmitted on a port. Rather, it limits the number of IGMP groups and source-groups, of which a port can be a member. It is the responsibility of the IPTV operator to configure subscriber membership requests to the appropriate multicast flows.

igmp snooping profile

To create or change an IGMP snooping profile, or to attach an IGMP snooping profile to a bridge or a port, use the igmp snooping profile command in the appropriate configuration mode. To detach a profile from a bridge domain or port, use the no form of this command. To delete a profile from the database, use the no form of this command in global configuration mode.

igmp snooping profile profile-name

no igmp snooping

Syntax Description

profile-name

Name that uniquely identifies the IGMP snooping profile.

Command Default

IGMP snooping is inactive on a bridge domain until a profile is attached to the bridge domain.

Command Modes

Global configuration

L2 VPN bridge group bridge domain configuration

L2 VPN bridge group bridge domain interface configuration

Command History

Release

Modification

Release 3.7.2

This command was introduced.

Usage Guidelines

This command accomplishes different tasks depending on the configuration mode you are in when you issue it.

  • In global configuration mode, this command creates and changes profiles.
  • In L2 VPN bridge group bridge domain configuration mode, this command attaches profiles to bridge domains.
  • In L2 VPN bridge group bridge domain interface configuration mode, this command attaches profiles to ports.

Use the igmp snooping profile command in global configuration mode to create a new IGMP snooping profile or to change an existing profile. The command enters you into IGMP snooping profile configuration mode, from which you can issue commands that configure IGMP snooping.

The minimum configuration is an empty profile. An empty profile enables IGMP snooping with a default configuration.

To enable IGMP snooping on a bridge domain, you must attach a profile to the bridge domain. To disable IGMP snooping on a bridge domain, detach the profile from the bridge domain.

To attach a profile to a bridge domain, use the igmp snooping profile command in Layer-2 VPN bridge group bridge domain configuration mode. At the bridge domain level, only one IGMP snooping profile can be attached to a bridge.

If a profile attached to a bridge domain contains port-specific configuration options, the values apply to all of the ports under the bridge, unless a port-specific profile is attached to one of the ports. In that case, the port with the attached profile is configured using only the commands in the port profile, and any port configurations in the bridge profile are ignored.

Optionally, profiles can be attached to specific ports under a bridge domain. To attach a profile to a port, use the igmp snooping profile command in Layer-2 VPN bridge group bridge domain interface configuration mode. Each port can have only one port-specific profile attached to it.

IGMP snooping must be enabled on the bridge domain for any port-specific configurations to take effect. When a profile is attached to a port, IGMP snooping reconfigures that port, disregarding any port configurations that may exist in the bridge-level profile.

To detach a profile from a bridge domain, use the no form of this command in Layer-2 VPN bridge group bridge domain configuration mode. To detach a profile from a port, use the no form of this command in the interface configuration mode under the bridge domain.

When you detach a profile from a bridge domain or a port, the profile still exists and is available for use at a later time.

Detaching a profile has the following results:

  • If you detach a profile from a bridge domain, IGMP snooping is deactivated in the bridge domain.
  • If you detach a profile from a port, IGMP snooping configuration values for the port are instantiated from the bridge domain profile.

An active profile is one that is currently attached.

If you need to change an active profile, you must detach it from all bridges or ports, change it, and reattach it. An alternate procedure is to create a new profile incorporating the desired changes, detach the existing one, and immediately attach the new one.

To access an existing profile, use the igmp snooping profile command with the existing profile-name in global configuration mode. The command enters you into IGMP snooping profile configuration mode, from which you can issue commands to add to the current configuration or enter the no form of existing commands to delete them from the configuration.

To delete a profile from the router database, use the no form of this command in global configuration mode.

RP/0/RSP0/CPU0:router(config-l2vpn-bg-bd-if)# commit

immediate-leave

To configure fast leave processing on a port for IGMPv2 / MLDv1 queriers, use the immediate-leave command in the appropriate snooping profile configuration mode. To remove the functionality, use the no form of this command.

immediate-leave

no immediate-leave

Syntax Description

This command has no arguments or keywords.

Command Default

Disabled

Command Modes

IGMP snooping profile configuration

MLD snooping profile configuration

Command History

Release

Modification

Release 3.7.2

This command was introduced.

Usage Guidelines

Immediate leave is an optional port-level configuration parameter. Immediate leave processing causes IGMP snooping to remove a Layer-2 interface from the forwarding table entry immediately, without first sending IGMP group-specific queries to the interface. Upon receiving an IGMP leave message, IGMP snooping immediately removes the interface from the Layer-2 forwarding table entry for that multicast group, unless a multicast router was learned on the port.

Immediate leave processing improves leave latency but is appropriate only when one receiver is configured on a port. For example, immediate leave is appropriate in the following situations:

  • Point-to-point configurations, such as an IPTV channel receiver.
  • Downstream DSLAMs with proxy reporting.

Caution


Do not use immediate leave on a port when the possibility exists for more than one receiver per port. Doing so could prevent an interested receiver from receiving traffic. For example, immediate leave is not appropriate in a LAN.


Immediate leave processing is a port-level option. You can configure this option explicitly per port in port profiles or in the bridge domain profile, in which case it applies to all ports under the bridge.

For MLD snooping - Immediate-leave should only be configured if there is a single MLD host on the port. Immediate-leave is implicitly enabled for MLDv2, if explicit-tracking is enabled.

Command History

Release

Modification

Release 3.7.2

This command was introduced.

Usage Guidelines

Use this command to configure an IGMP querier in a bridge domain where no external querier exists. An internal querier injects query packets into the bridge domain.

In a network where IP multicast routing is configured, the IP multicast router acts as the IGMP querier. In situations when no mrouter port exists in the bridge domain (because the multicast traffic does not need to be routed), but local multicast sources exist, you must configure an internal querier to implement IGMP snooping. The internal querier solicits membership reports from hosts in the bridge domain so that IGMP snooping can build constrained multicast forwarding tables for the multicast traffic within the bridge domain.

An internal querier might also be useful when there are interoperability issues that prevent IGMP snooping from working correctly with an external querier. In this case, you can:

  1. Prevent the uncooperative external querier from being discovered by placing the router-guard command on that port.
  2. Configure an internal querier to learn group membership interests from the ports in the bridge domain.
  3. Configure static mrouter ports to receive multicast traffic.

The minimum configuration for an internal querier is as follows. Both of the following commands are required.

  • Add the internal-querier command to a profile attached to the bridge domain. This command configures the internal querier with the default configuration.
  • Add the system-ip-address command to a profile attached to the bridge domain to configure an address other than the default 0.0.0.0.

You can disable the internal querier (using the no form of the internal-querier command) without removing any other internal querier commands. The additional internal querier commands are ignored in that case.

The scope for the internal-querier command is per bridge domain. If the command appears in profiles attached to ports, it has no effect.

The local IGMP snooping process responds to the internal querier's general queries. In particular, the IGMPv3 proxy (if enabled) generates a current-state report and forwards it to all mrouters. For IGMPv2 or when the IGMPv3 proxy is disabled, IGMP snooping generates current-state reports for static group state only.

Usage Guidelines

The internal-querier is disabled by default. However, if PIMv6 snooping is active in the domain, then the internal-querier is active. If queries are received from another querier in the domain, MLD querier election is performed (where the lowest ip-address wins). If the internal-querier is the election-loser, then a timer (the other-querier-present-timer) is run for the timer expiry interval. If this timer expires before another query is received from the election-winner, then the internal-querier becomes the querier.

Usage Guidelines

The maximum response time (MRT) is the amount of time during which receivers are required to report their membership state.

In addition, the maximum response time is used in the calculation of the Group Management Interval (GMI). GMI controls when IGMP snooping expires stale group membership states. See the “Implementing IGMP Snooping on Cisco ASR 9000 Series Router” module in the Cisco ASR 9000 Series Routers Multicast Configuration Guide for more information about the GMI.

The maximum response time is advertised in general queries issued by the internal querier.

Usage Guidelines

A bridge domain can have only one active querier at a time. If the internal querier receives queries from another querier in a bridge domain, it performs querier election. The lowest IP address wins. If the internal querier is the election loser, the snooping technique sets a timer to the internal-querier timer expiry value. If this timer expires before another query is received from the election winner, the internal querier becomes the active querier.

Usage Guidelines

Last member query is the default group leave processing method used by IGMP snooping. With last member query processing, IGMP snooping processes leave messages as follows:

  • IGMP snooping sends group-specific queries on the port that receives the leave message to determine if any other devices connected to that interface are interested in traffic for the specified multicast group. Using the following two configuration commands, you can control the latency between the request for a leave and the actual leave:
    • last-member-query-count command—Controls the number of group-specific queries IGMP snooping sends in response to a leave message.

    • last-member-query-interval command—Controls the amount of time between group-specific queries.

  • If IGMP snooping does not receive an IGMP Join message in response to group-specific queries, it assumes that no other devices connected to the port are interested in receiving traffic for this multicast group, and it removes the port from its Layer-2 forwarding table entry for that multicast group.
  • If the leave message was from the only remaining port, IGMP snooping removes the group entry and generates an IGMP leave to the multicast routers.

Usage Guidelines

You can statically configure a port as an mrouter port with the mrouter command.

You can use the router-guard and the mrouter commands on the same port to configure a guarded port as a static mrouter. For example:

  • In situations where there are a large number of downstream host ports, you may want to block dynamic mrouter discovery and configure static mrouters. In this case, configure the router guard feature at the domain level. By default, it will be applied to all ports, including the (typically) large number of downstream host ports. Then use another profile without router guard configured for the relatively few upstream ports on which you want to permit dynamic mrouter discovery or configure static mrouters.
  • In situations when incompatibilities with non-Cisco equipment prevents correct dynamic discovery, you can disable all attempts for dynamic discovery using the router guard feature, and statically configure the mrouter.

    If you are using the router guard feature because there is an incompatible IGMP router on the port, you should also configure the mrouter command on the port to ensure that the router receives snooping reports and multicast flows.

The scope of this command is port level. If you use this command in a profile attached to a bridge domain, you are configuring all ports as mrouter ports.

Usage Guidelines

Query interval is the interval between general queries and is used in the calculated group management interval (GMI). GMI controls when IGMP snooping expires stale group membership states. For more information about GMI, see the “Implementing IGMP Snooping on Cisco ASR 9000 Series Routers” module in the Cisco ASR 9000 Series Routers Multicast Configuration Guide.

If the querier is running IGMPv2, IGMP snooping uses the IGMP snooping configured values for robustness variable and query interval. These parameter values must match the configured values for the querier. In most cases, if you are interacting with other Cisco routers, you should not need to explicitly configure these values—the default values for IGMP snooping should match the default values of the querier. If they do not, use the querier robustness-variable and querier query-interval commands to configure matching values.


Note


Cisco IOS and Cisco IOS XR software use the nonstandard default value of 60 for query interval.



Note


IGMPv3 general queries convey values for robustness variable and query interval (QRV and QQI, respectively). IGMP snooping uses the values from the query, making the IGMP snooping GMI exactly match that of the querier.

  • IGMPv2 report suppression—For IGMPv2 bridge domain queriers, IGMP snooping suppresses reports from a host if the report was previously forwarded from another host. IGMP snooping sends only the first join and last leave to mrouter ports.
  • IGMPv3 proxy reporting—For IGMPv3 bridge domain queriers, IGMP snooping acts as a proxy, generating state change reports from a proxy reporting IP address. You can configure that IP address using the system-ip-address command. The default is 0.0.0.0.

These features are enabled and disabled per bridge domain. This command is ignored if it appears in a profile attached to a port.

Description

igmp snooping profile

Creates or edits a profile, and attaches a profile to a bridge domain or port.

system-ip-address

Configures an IP address used by IGMP snooping.

report-suppression disable(MLD)

To minimize the number of MLD reports sent to the mrouters, use the report-suppression disable command in the MLD snooping profile configuration mode.

report-suppression disable

no report-suppression disable

Syntax Description

This command has no keywords or arguments.

Command Default

By default, report suppression is enabled.

Command Modes

MLD snooping profile configuration mode.

Command History

Release Modification

Release 4.3.0

This command was introduced.

Usage Guidelines

The report suppression command instructs MLD Snooping to suppress the forwarding of reports from individual hosts and instead to send the first-join and last-leave reports to the mrouters.

If the querier in the BD is running at MLD version 1, then report-suppression is performed and the snooper suppresses reports from a host if it has already forwarded the same report from another host. If the querier is on version 2, then proxy-reporting is performed. In this mode, the snooper acts as a proxy, generating reports from the proxy reporting IP address.

Modification

Release 3.7.2

This command was introduced.

Usage Guidelines

By default, IGMP snooping checks for the presence of the router alert option in the IP packet header of the IGMP message and drops packets that do not include this option. If your network performs this validation elsewhere, you can disable this IGMP snooping validation.

You can disable this check using the router-alert-check disable command, in which case IGMP snooping does perform the validation before processing the message.

The scope for this configuration option is per bridge domain. If the command appears in profiles attached to ports, it has no effect.

Usage Guidelines

Router guard is a security feature that prevents malicious users from making a host port into an mrouter port. (This undesirable behavior is known as spoofing.) When a port is protected with the router-guard command, it cannot be dynamically discovered as an mrouter. When router guard is on a port, IGMP snooping filters protocol packets sent to the port and discards any that are multicast router control packets.


Caution


If you add the router-guard command in a bridge domain profile, you disable dynamic discovery of all mrouters in that bridge domain.


You can use the router-guard and the mrouter commands on the same port to configure a guarded port as a static mrouter. For example:

  • In situations where there are a large number of downstream host ports, you may want to block dynamic mrouter discovery and configure static mrouters. In this case, configure the router guard feature at the domain level. By default, it will be applied to all ports, including the (typically) large number of downstream host ports. Then use another profile without router guard configured for the relatively few upstream ports on which you want to permit dynamic mrouter discovery or configure static mrouters.
  • In situations when incompatibilities with non-Cisco equipment prevents correct dynamic discovery, you can disable all attempts for dynamic discovery using the router guard feature, and statically configure the mrouter.

    If you are using the router guard feature because there is an incompatible IGMP router on the port, you should also configure the mrouter command on the port to ensure that the router receives reports and multicast flows.

Usage Guidelines

Use this command to display information about group membership in the Layer -2 forwarding tables. The display includes indicators identifying whether the group information was obtained dynamically (for example, snooped) or statically configured.

The command offers the following levels of detail:

  • The basic command with no keywords displays group membership information as one line per port within group.
  • The summary keyword summarizes the port statistics into one line per group. The summary keyword is mutually exclusive with the port-view, source, and detail keywords.
  • The detail keyword includes traffic statistics and counters.

Clears group states.

show igmp snooping port

To display IGMP snooping configuration information and traffic counters by router interface port, use the show igmp snooping port command in EXEC mode.

show igmp snooping portinterface-name | neighbor ipaddr pw-id id | bridge-domain bridge-domain-name detail [ statistics [include-zeroes] ] group[ group-address ] [ source source-address ] [detail]

Syntax Description

interface-name

(Optional) Displays information only for the specified AC port.

neighbor ipaddr pw-id id

(Optional) Displays information only for the specified PW port.

bridge-domain bridge-domain-name

(Optional) Displays information for ports in the specified bridge domain.

detail

(Optional) Includes port details, rather than a single line summary.

statistics

(Optional) Includes IGMP traffic counters and statistics in the detail display.

include-zeroes

(Optional) Includes all statistics, even if they are zero. Without this keyword, many statistics are omitted from the display when their values are zero.

group

(Optional) Provides group membership information in its entirety as received at each port. The display is organized by port, showing groups within ports.

group-address

Command History

Release

Modification

Release 3.7.2

This command was introduced.

Release 3.9.0

The total group weight accumulated by all groups and source groups on the port, the configured limit, access group permits, access group denials, and group limits exceeded fields were added to the detail display output.

Usage Guidelines

This command displays IGMP snooping information organized by IGMP snooping port. Use the command without any keywords to display summary information about all ports, in a single line per port.

Use optional arguments and keywords to request the following:

  • Limit the display to a specified port.
  • Limit the display to ports under a specified bridge.
  • Request details and traffic statistics per port.

    Note


    The statistics keyword cannot be used in the same command with the group keyword.


  • Organize the display by group within ports. Use the group keyword with or without a specified interface or bridge domain.
  • Limit the group information to specific groups or source addresses.

The statistics keyword displays IGMP traffic information, including IGMP queries, reports, and leaves. The three columns in the statistics section of the display are:

  • Received—Number of packets received.
  • Reinjected—Number of packets received, processed, and reinjected back into the forwarding path.
  • Generated—Number of packets generated by the IGMP snooping application and injected into the forwarding path.

show l2vpn forwarding bridge-domain mroute

To display multicast routes in the forwarding tables, use the show l2vpn forwarding bridge-domain mroute command in EXEC mode.

show l2vpn forwarding bridge-domain [ bridge-group-name : bridge-domain-name ] mroute [ipv4] location rack /slot /module

Syntax Description

bridge-group-name bridge-domain-name

(Optional) Displays information for a specific bridge domain. The colon that separates the two arguments is required.

ipv4

This keyword is required.

location rack/slot/module

Displays route information for a specific rack/slot/module.

Command Default

Command History

Release

Modification

Release 3.7.2

This command was introduced.

Release 5.2.2

The show output command was enhanced to include the satellite multicast offload information.

Usage Guidelines

This command displays multicast routes as they are converted into the forwarding plane forwarding tables. The source for the conversion is the multicast routes configured in the control plane with IGMP snooping configuration commands. If the routes displayed by this command are not as expected, check the control plane configuration and correct the corresponding IGMP snooping profiles.

Use optional arguments to limit the display to a specific bridge domain.

Usage Guidelines

This command displays mld snooping information by bridge domain. Use the command without any keywords to display summary information about all bridge domains, in a single line per bridge domain.

Use optional keywords to request additional details and traffic statistics per bridge domain. You can also limit the display to a single bridge domain.

The statistics keyword displays mld traffic information, including mld queries, reports, and leaves. The three columns in the statistics section of the display are:

  • Received—Number of packets received.
  • Reinjected—Number of packets received, processed, and reinjected back into the forwarding path.
  • Generated—Number of packets generated by the mld snooping application and injected into the forwarding path.

This command was introduced.

Usage Guidelines

Use this command to display information about group membership in the Layer -2 forwarding tables. The display includes indicators identifying whether the group information was obtained dynamically (for example, snooped) or statically configured.

The command offers the following levels of detail:

  • The basic command with no keywords displays group membership information as one line per port within group.
  • The summary keyword summarizes the port statistics into one line per group. The summary keyword is mutually exclusive with the port-view, source, and detail keywords.
  • The detail keyword includes traffic statistics and counters.

This command was introduced.

Usage Guidelines

This command displays mld snooping information organized by mld snooping port. Use the command without any keywords to display summary information about all ports, in a single line per port.

Use optional arguments and keywords to request the following:

  • Limit the display to a specified port.
  • Limit the display to ports under a specified bridge.
  • Request details and traffic statistics per port.

    Note


    The statistics keyword cannot be used in the same command with the group keyword.


  • Organize the display by group within ports. Use the group keyword with or without a specified interface or bridge domain.
  • Limit the group information to specific groups or source addresses.

The statistics keyword displays mld traffic information, including mld queries, reports, and leaves. The three columns in the statistics section of the display are:

  • Received—Number of packets received.
  • Reinjected—Number of packets received, processed, and reinjected back into the forwarding path.
  • Generated—Number of packets generated by the mld snooping application and injected into the forwarding path.

show mld snooping profile

To display MLD snooping profile information, use the show mld snooping profile command in EXEC mode.

{ show mld snooping profile [summary] | [profile-name] [ detail [include-defaults] ] [ references [ bridge-domain [bridge-domain-name] ] | port [ interface-name | neighbor ipaddr pw-id id ] ] }

Syntax Description

summary

(Optional) Displays a summary of profile instances, bridge domain references, and port references.

profile-name

(Optional) Displays information only for the named profile.

detail

(Optional) Displays the contents of profiles.

include-defaults

(Optional) Displays all default configurations with the profile contents. Without this keyword, only configured profile information is displayed.

references

(Optional) Shows which bridge domains and bridge ports reference each profile.

bridge-domain [bridge-domain-name]

(Optional) Provides a bridge domain filter for the references keyword.

Without bridge-domain-name , the display shows profiles attached to all bridge domains. With bridge-domain-name , the display shows only the profile attached to the specified bridge domain.

port [interface-name]

or

port [neighbor ipaddr pw-id id]

(Optional) Provides a port filter for the references keyword.

  • With interface-name or neighbor specified, the display shows the profile attached to the named AC or PW.
  • Using the port keyword alone shows profiles attached to all ports.

Modification

Release 4.3.0

This command was introduced.

Usage Guidelines

Use this command to display the contents of profiles and to see associations of profiles with bridge-domains and ports.

The summary keyword lists profile names and summarizes their usage on bridge domains and ports. No other keywords can be used with summary .

Use the details keyword with a profile name to show the contents of a specific profile. Without a profile name, the detail keyword shows the contents of all profiles.

Use the references keyword to list the relationships between profiles and bridge domains or profiles and ports. You have the following options:

  • Use the references keyword without any other keywords to show all profiles and the ports and bridge domains they are attached to.
  • Use the references keyword with the name keyword to show a specific profile and where it is attached.
  • Use the port keyword to list all ports and the profiles attached to them.
  • Use the port keyword with a specific AC interface or PW to see the profile attached to the named port.
  • Use the bridge-domain keyword to list all bridge domains and the profiles attached to them.
  • Use the bridge-domain keyword with a specific bridge domain name to see the profile attached to a specific bridge domain.

Modification

Usage Guidelines

IGMP snooping learns Layer-2 multicast groups dynamically. You can also statically configure Layer-2 multicast groups.

You can use the static group command in profiles intended for bridge domains or ports. I f you configure this option in a profile attached to a bridge domain, it applies to all ports under the bridge.

A profile can contain multiple static groups. You can define different source addresses for the same group address. Using the source keyword, you can configure IGMPv3 source groups.

Static group membership supersedes any dynamic manipulation by IGMP snooping. Multicast group membership lists can contain both static and dynamic group definitions.

When you configure a static group or source group on a port, IGMP snooping adds the port as an outgoing port to the corresponding <S/*,G> forwarding entry and sends an IGMPv2 join or IGMPv3 report to all mrouter ports. IGMP snooping continues to send the membership report in response to general queries for as long as the static group remains configured on the port.

The scope of this command can be either bridge domain level or port level. If you use this command in a profile attached to a bridge domain, the static group membership applies to all ports under the bridge. If you use the command in a profile attached to a port, the static group membership applies only to that port.

Modification

Release 3.7.2

This command was introduced.

Usage Guidelines

The system-ip-address command configures an IP address for IGMP snooping use. If not explicitly configured, the default address is 0.0.0.0. The default is adequate except in the following circumstances:

  • If you are configuring an internal querier. The internal querier cannot use 0.0.0.0.
  • If the bridge needs to communicate with a non-Cisco IGMP router that does not accept the 0.0.0.0 address.

IGMP snooping uses the value set by the system-ip-address command in the following ways:

  • The internal-querier sends queries from the system IP address. An address other than the default 0.0.0.0 must be configured.
  • IGMPv3 sends proxy reports from the system IP address. The default address 0.0.0.0 is preferred but may not be acceptable to some IGMP routers.
  • In response to topology change notifications (TCNs) in the bridge domain, IGMP snooping sends global-leaves from the system IP address. The default address 0.0.0.0 is preferred but may not be acceptable to some IGMP routers.

Usage Guidelines

In a Spanning Tree Protocol (STP) topology, a topology change notification (TCN) indicates that an STP topology change has occurred. As a result of a topology change, mrouters and hosts reporting group membership may migrate to other STP ports under the bridge domain. Mrouter and membership states must be relearned after a TCN.

IGMP snooping reacts to TCNs in the following way:

  1. IGMP snooping temporarily extends the flood set for all known multicast routes to include all ports participating in STP that are in forwarding state. The short term flooding ensures that multicast delivery continues to all mrouters and all member hosts in the bridge domain while mrouter and membership states are relearned.
  2. The STP root bridge issues a global leave (leave for group 0.0.0.0) on all ports. This action triggers mrouters to send general queries, expediting the relearning process.


    Note


    Sending global leaves for query solicitation is a Cisco-specific implementation.


  1. When the TCN refresh period ends, IGMP snooping withdraws the non-mrouter and non-member STP ports from the multicast route flood sets. You can control the amount of time that flooding occurs with the tcn flood query count command. This command sets the number of IGMP general queries for which the multicast traffic is flooded following a TCN, thus influencing the refresh period.

IGMP snooping default behavior is that the STP root bridge always issues a global leave in response to a TCN, and the non-root bridges do not issue global leaves.

With the tcn query solicit command, you can enable a bridge to always issue a global leave in response to TCNs, even when it is not the root bridge. In that case, the root bridge and the non-root bridge would issue the global leave and both would solicit general queries in response to a TCN. Use the no form of the command to turn off soliciting when the bridge is not the root.

The root bridge always issues a global leave in response to a TCN. This behavior can not be disabled.

The internal querier has its own set of configuration options that control its reactions to TCNs.

The scope for this configuration option is per bridge domain. If the command appears in profiles attached to ports, it has no effect.
