Multicast Routing and Forwarding Commands

This module describes the commands used to configure and monitor multicast routing.

For detailed information about multicast routing concepts, configuration tasks, and examples, refer to the Implementing Multicast Routing on Cisco IOS XR Software configuration module in the Multicast Configuration Guide for Cisco ASR 9000 Series Routers.

To use commands of this module, you must be in a user group associated with a task group that includes appropriate task IDs. If the user group assignment is preventing you from using any command, contact your AAA administrator for assistance.

accounting per-prefix

To enable accounting for multicast routing, use the accounting per-prefix command in the appropriate configuration mode. To return to the default behavior, use the no form of this command.

accounting per-prefix

Syntax Description

This command has no keywords or arguments.

Command Default

This feature is disabled by default.

Command Modes

Multicast routing configuration

Multicast routing address family IPv4 configuration

Multicast VRF configuration

Command History

Release

Modification

Release 3.7.2

This command was introduced.

Usage Guidelines

The accounting per-prefix command is used to enable per-prefix counters only in hardware. Cisco IOS XR Software counters are always present. When enabled, every existing and new (S, G) route is assigned forward, punt, and drop counters on the ingress route and forward and punt counters on the egress route. The (*, G) routes are assigned a single counter.

There are a limited number of counters on all nodes. When a command is enabled, counters are assigned to routes only if they are available.

To display packet statistics, use the show mfib route and the show mfib hardware route statistics commands. These commands display “N/A” for counters when no hardware statistics are available or whenthe accounting per-prefix command is disabled .

Task ID

Operations

multicast

read, write

Examples

The following example shows how to enable accounting for multicast routing: 


RP/0/RSP0/CPU0:router(config)# multicast-routing
RP/0/RSP0/CPU0:router(config-mcast)# accounting per-prefix

Related Commands

Command Description

show mfib hardware route statistics

Displays platform-specific Multicast Forwarding Information Base (MFIB) information for the packet and byte counters for each route.  

show mfib route

Displays route entries in the Multicast Forwarding Information Base (MFIB). 

accounting per-prefix forward-only

To reduce hardware statistics resource allocations when enabling accounting, particularly for multicast VPN (MVPN), use the accounting per-prefix forward-only command under multicast routing configuration mode. To return to the default mode of accounting per-prefix, use the no form of this command.

accounting per-prefix forward-only

Syntax Description

This command has no keywords or arguments.

Command Default

If no counters are configured, there is no default.

If the accounting per-prefix counter was previously configured, it becomes the default.

If no accounting was configured for multicast routing, forwarding-only is the default mode and triggers a data MDT transition in the case of MVPN deployment.

Command Modes

Multicast routing configuration

Multicast routing address family IPv4 and IPv6 configuration

Multicast VRF configuration

Command History

Release

Modification

Release 3.8.0

This command was introduced.

Usage Guidelines


Note

The accounting per-prefix forward-only command has only one fwd-only counter. In other words, there is no punt or drop counter allocated.

We recommend this command for configuration of multicast VPN routing or for any line card that has a route-intensive configuration. Each individual router can support up to 150,000 routes.


Note

To verify the number of statistics allocated or free on a line card, use the show mfib hardware resource-counters command in EXEC mode.

There are a limited number of counters on all nodes. When accounting on a prefix is enabled, counters are assigned to routes only if they are available.

To display packet statistics, use the show mfib route and the show mfib hardware route statistics commands. These commands display “N/A” for counters when no hardware statistics are available or when neither the accounting per-prefix command nor the accounting per-prefix forward-only command are enabled.

You may switch between accounting-perprefix and accounting per-prefix forward-only statistics for ipv4 or ipv6 multicast family. However, be aware that only one set of counters is supported on the (*,G) routes (with fwd/punt/drop on ingress and fwd/drop on egress) regardless of whether you enabled the accounting-perprefix or accounting-perprefix fwd-only command.

Although you can switch accounting modes, this involves freeing the hardware statistics and reallocating them, thereby resulting in a loss of any previously collected data. Therefore, it is preferable to decide which statistics mode you want to use at the start to avoid the resource cost entailed by resetting the statistics counter values with a change in mode.

Command Description

accounting per-prefix

Enables accounting for multicast routing.  

clear mfib hardware resource-counters

Clears global resource counters.  

address-family (multicast)

To display available IP prefixes to enable multicast routing and forwarding on all router interfaces, use the address-family command in multicast-routing configuration mode or multicast VRF configuration submode. To disable use of an IP address prefix for routing, use the no form of this command.

address-family [vrf vrf-name] {ipv4 | ipv6}

Syntax Description

vrf vrf-name

(Optional) Specifies a VPN routing and forwarding (VRF) instance.

ipv4

Specifies IPv4 address prefixes.

ipv6

Specifies IPv6 address prefixes.

Command Default

No default behavior or values

Command Modes

Multicast routing configuration

Multicast VRF configuration

Command History

Release

Modification

Release 3.7.2

This command was introduced.

Release 4.2.0

The ipv6 keyword was added.

Usage Guidelines

Use the address-family command either from multicast routing configuration mode or from multicast VRF configuration sub to enter either the multicast IPv4 or IPv6 address family configuration submode, depending on which keyword was chosen. Use the address-family command with the multicast-routing command to start the following multicast processes:

  • Multicast Routing Information Base (MRIB)
  • Multicast Forwarding Engine (MFWD)
  • Protocol Independent Multicast Sparse mode (PIM-SM)
  • Internet Group Management Protocol (IGMP)
  • Multicast Listener Discovery Protocol (MLD)

Basic multicast services start automatically when the multicast PIE is installed, without any explicit configuration required. The following multicast services are started automatically:

  • Multicast Routing Information Base (MRIB)
  • Multicast Forwarding Engine (MFWD)
  • Protocol Independent Multicast Sparse mode (PIM-SM)
  • Internet Group Management Protocol (IGMP)

Other multicast services require explicit configuration before they start. For example, to start the Multicast Source Discovery Protocol (MSDP) process, you must enter the router msdp command and explicitly configure it.

To enable multicast routing and protocols on interfaces, you must explicitly enable the interfaces using the interface command in multicast routing configuration mode. This action can be performed on individual interfaces or by configuring a wildcard interface using the alias command.

To enable multicast routing on all interfaces, use the interface all enable command in multicast routing configuration mode. For any interface to be fully enabled for multicast routing, it must be enabled specifically (or configured through the interface all enable command for all interfaces) in multicast routing configuration mode, and it must not be disabled in the PIM and IGMP configuration modes.


Note

The enable and disable keywords available under the IGMP and PIM interface configuration modes have no effect unless the interface is enabled in multicast routing configuration mode—either by default or by explicit interface configuration.

To allow multicast forwarding functionality, while turning multicast routing functionality off, interface-inheritance disable command on a per interface or interface all enable basis in PIM or IGMP configuration mode.

Command Modes

Command History

Release

Modification

Release 3.7.2

This command was introduced.

Usage Guidelines

To use this command, you must be in a user group associated with a task group that includes the proper task IDs.

The Multicast Forwarding (MFWD) process exists on each line card and assigns hardware counters to each (S, G) route. Additionally, one global counter is assigned for all (*, G) routes, depending on resource availability.

To clear the set of counters for (*, G) routes, the MFWD process assigns a single set of counters to count packets that match (*, G) routes. Consequently, the clear mfib hardware route statistics command must be used in a form that either clears counters on all routes or matches all (*, G) routes.


Note

This command only clears MFIB hardware statistics counters. To clear MFIB route packet software counters, use the clear mfib counter command.

Task ID

Task ID

Operations

multicast

The following guidelines apply when the enable and disable commands (and the no forms) are used in conjunction with the interface all enable command:

  • If the interface all enable command is configured:

    • The enable and no forms of the command have no additional effect on a specific interface.

    • The disable command disables multicast routing on a specific interface.

    • The no disable command enables a previously disabled interface.

  • If the interface all enable command is not configured:

    • The enable command enables multicast routing on a specific interface.

    • The no enable command enables the previously disabled interface.

    • The disable and no forms of the command have no additional effect on a specific interface.

Disables multicast routing and forwarding on an interface.  

interface all enable

Enables multicast routing and forwarding on all new and existing interfaces.  

forwarding-latency

To delay traffic being forwarded on a route, use the forwarding-latency command. To return to the default behavior, use the no form of this command.

forwarding-latency [delay milliseconds]

Syntax Description

delay milliseconds

(Optional) Specifies the delay time in miliseconds. Range is 5 - 500.

Command Default

The default delay time is 30 milliseconds.

Command Modes

Multicast routing configuration

IPv4 and IPv6 multicast routing configuration

Command History

Release

Modification

Release 3.8.0

This command was introduced.

Usage Guidelines

Use the forwarding-latency command when you expect a receiver to leave and rejoin the same multicast group within a very short period such as 20 or 30 milliseconds. The delay may be required to provide the router sufficient time to update its Multicast Forwarding Information Base (MFIB) table.

When the forwarding-latency command is enabled, each interface is allocated a separate table lookup unit (TLU) block in the output interface list (olist), thereby increasing TLU hardware resource usage, and, for this reason, it should be used with caution when many multicast routes are present.

When the forwarding-latency command is disabled, up to three interfaces may share a single TLU block in the olist.

interface-inheritance disable

To separate PIM and IGMP routing from multicast forwarding on all interfaces, use the interface-inheritance disable command under multicast routing address-family IPv4 submode. To restore the default functionality, use the no form of the command.

interface-inheritance disable

This command has no keywords or arguments.

Command Default

This feature is not enabled by default.

Command Modes

Modification

Release 3.7.2

This command was introduced.

Usage Guidelines

Use of the interface-inheritance disable command together with the interface type interface-path-id or interface all enable command under multicast routing address-family IPv4 submode separates PIM and IGMP routing functionality from multicast forwarding on specified interfaces. You can nonetheless enable multicast routing functionality explicitly under PIM or IGMP routing configuration mode for individual interfaces.


Note

Although you can explicitly configure multicast routing functionality on individual interfaces, you cannot explicitly disable the functionality. You can only disable the functionality on all interfaces.

Used from the address-family ipv4 configuration submode, it prevents IGMP and PIM from inheriting the multicast-routing interface configuration.

Examples

The following configuration disables PIM and IGMP routing functionality on all the interfaces using the interface-inheritance disable command, but multicast forwarding is still enabled on all the interfaces in the example, based on use of the keywords interface all enable .

PIM is enabled on Loopback 0 based on its explicit configuration ( interface Loopback0 enable ) under router pim configuration mode.

IGMP protocol is enabled on GigabitEthernet0/6/0/3, because it too has been configured explicitly under router igmp configuration mode ( interface GigabitEthernet0/6/0/3 router enable ): 


RP/0/RSP0/CPU0:router(config)# multicast-routing 
RP/0/RSP0/CPU0:router(config-mcast)# address-family ipv4 
RP/0/RSP0/CPU0:router(config-mcast-default-ipv4)# interface-inheritance disable 
RP/0/RSP0/CPU0:router(config-mcast-default-ipv4)# interface loopback 1 enable 

RP/0/RSP0/CPU0:router(config-mcast-default-ipv4)# show run router pim

With the interface-inheritance disable command in use, IGMPand PIM configuration are enabled in the protocol configuration as follows: 


router igmp

Command History

Modification

Release 3.7.2

This command was introduced.

Usage Guidelines

The mhost default-interface command configures the interface that the automatic route processing (Auto-RP), ping, and mtrace applications use for multicast transmissions, and the interface to which multicast groups are joined for reception.

The ping and mtrace features may use the MHost default interface to process multicast messaging. When IP multicast routing is enabled, packets sent to the MHost default interface are switched on other interfaces with a matching forwarding state. In addition, an arbitrary interface may be chosen to be the active MHost default interface if the configured interface is not operational. If no MHost default interface is configured with this command, an arbitrary interface is selected as the active MHost default.


Note
  • The MHost default interface must be configured explicitly (preferably use a loopback interface).
  • If the MHost default interface is not configured explicitly, then the router picks an interface.
  • If the router picked multicast interface happens to be an ASBR link (on an ASBR router) and if that interface is configured with multicast boundary, then it may not work as intended beacuse there is an IC (Internal Copy) flag on the interface and it has to accept all multicast packets on the interface.

nsf (multicast)

To turn on the nonstop forwarding (NSF) capability for the multicast routing system, use the nsf command in multicast routing configuration mode. To turn off this function, use the no form of this command.

Command Default

This command is disabled by default.

Command Modes

Command History

Release

Modification

Release 3.7.2

This command was introduced.

Usage Guidelines

The nsf command does not enable or disable the multicast routing system, but just the NSF capability for all the relevant components. When the no form of this command is used, the NSF configuration is returned to its default disabled state.

Enable multicast NSF when you require enhanced availability of multicast forwarding. When enabled, failures of the control-plane multicast routing components Multicast Routing Information Base (MRIB) or Protocol Independent Multicast (PIM) will not cause multicast forwarding to stop. When these components fail or communication with the control plane is otherwise disrupted, existing Multicast Forwarding Information Base (MFIB) entries continue to forward packets until either the control plane recovers or the MFIB NSF timeout expires.

Enable multicast NSF when you upgrade control-plane Cisco IOS XR Software packages so that the live upgrade process does not interrupt forwarding.

When the MFIB partner processes enter NSF mode, forwarding on stale (nonupdated) MFIB entries continues as the control-plane components attempt to recover gracefully. Successful NSF recovery is signaled to the Multicast Forwarding Engine (MFWD) partner processes by MRIB. MRIB remains in NSF mode until Internet Group Management Protocol (IGMP) has recovered state from the network and host stack and until PIM has recovered state from the network and IGMP. When both PIM and IGMP have recovered and fully updated the MRIB, MRIB signals the MFIBs that NSF is ending, and begins updating the stale MFIB entries. When all updates have been sent, the MFWD partner processes delete all remaining stale MFIB entries and returns to normal operation, ending the NSF mode. MFIB NSF timeout prior to the signal from MRIB may cause NSF to end, and thus forwarding to stop.

When forwarding is in NSF mode, multicast flows may continue longer than necessary when network conditions change due to multicast routing protocols, unicast routing protocol reachability information, or local sender and receiver changes. The MFWD partner processes halt forwarding on stale MFIB entries when the potential for a multicast loop is detected by receipt of incoming data on a forwarding interface for the matching MFIB entry.


Note

For NSF to operate successfully in your multicast network, you must also enable NSF for the unicast protocols (such as Intermediate System-to-Intermediate System [IS-IS], Open Shortest Path First [OSPF] and Border Gateway Protocol [BGP]) that PIM relies on for Reverse Path Forwarding (RPF) information. See the appropriate configuration modules to learn how to configure NSF for unicast protocols.

Usage Guidelines

MoFRR is a mechanism in which two copies of the same multicast stream flow through disjoint paths in the network. At the point in the network (usually the PE closer to the receivers) where the two streams merge, one of the streams is accepted and forwarded on the downstream links, while the other stream is discarded. When a failure is detected in the primary stream due to a link or node failure in the network, MoFRR instructs the forwarding plane to start accepting packets from the backup stream (which now becomes the primary stream).

MoFRR is triggered when the hardware detects traffic loss on the primary path of a given flow or route. Traffic loss is defined as no data packet having been received for 30 ms. When MoFRR is triggered, the primary and secondary reverse-path forwarding (RPF) interfaces are exposed to the forwarding plane and switchover occurs entirely at the hardware level.

The show mfib hardware route mofrr command displays the output MoFRR route list of the platform. If there is no MoFRR route enabled in the platform, then the output result is “There are no MoFRR routes configured”.

The command does not display any useful output if only RSP is specified or if no location is specified.

This table describes the significant fields shown in the display.

Table 5. show mfib hardware route mofrr Field Descriptions

Field

Description

RPFS

Primary and backup RPF of the route.

A

Currently active RPF for forwarding the traffic to the egress (OLIST). T: means true, F: means false.

MS

Monitoring state. It has three states. MS=0, indicates that the monitoring state disabled. MS=1, indicates that active RPF is monitoring traffic activity. MS=2, indicates that active RPF is monitoring traffic loss.

WDI

Watchdog Count Index. Each MoFRR route has two Line card specific watchdog indexes, associated with primary and backup RPF, respectively.

OIFS

Output Interfaces in the local line card.

Sequence num

MoFRR specific route sequence number.

Num of switchovers

Total number of switchovers triggered by traffic loss detection in the data plane.

Watchdog Counters

Internal Hardware watchdog counters

MoFRR Statistics

Internal software watchdog counters

If there is no MoFRR route enabled in the platform, the output result will be as follows: 


RP/0/RSP0/CPU0:router# show mfib hardware route mofrr location 0/0/CPU0 

LC Type: Trident
No matching routes in MFIB
There are no MoFRR routes configured.

Related Commands

Command Description

show mfib hardware route olist

Displays platform-specific Multicast Forwarding Information Base (MFIB) information in the output interface list (olist) stored in the hardware.  

show mfib hardware route statistics

Displays platform-specific Multicast Forwarding Information Base (MFIB) information for the packet and byte counters for each route.  

show mfib hardware route summary

Displays summary platform-specific Multicast Forwarding Information Base (MFIB) hardware information for each route entry.  

show mfib route

Displays route entries in the Multicast Forwarding Information Base (MFIB). 

show mrib route

Displays all entries in the Multicast Routing Information Base (MRIB).  

show mfib hardware route olist

To display platform-specific Multicast Forwarding Information Base (MFIB) information in the output interface list (olist) stored in the hardware, use the show mfib hardware route olist command in the appropriate mode.

show mfib [vrf vrf-name] [ipv4 | ipv6] hardware route olist { [*] | [source-address] [group-address [/ prefix-length]]} [location node-id]

Syntax Description

vrf vrf-name

(Optional) Specifies a VPN routing and forwarding (VRF) instance.

ipv4

(Optional) Specifies IPv4 address prefixes.

ipv6

(Optional) Specifies IPv6 address prefixes.

*

(Optional) Displays shared tree entries.

source-address

(Optional) IP address or hostname of the multicast route source.

group-address

(Optional) IP address or hostname of the multicast group.

/ prefix-length

(Optional) Prefix length of the multicast group. A decimal value that indicates how many of the high-order contiguous bits of the address compose the prefix (the network portion of the address). A slash must precede the decimal value.

location node-id

Specifies an MFIB-designated node.

Command Default

IPv4 addressing is the default.

Command Modes

EXEC

Command History

Release

Modification

Release 3.7.2

This command was introduced.

Usage Guidelines

The show mfib hardware route olist command displays the output interface list (olist) for each route. The Multicast Forwarding (MFWD) process stores olist interfaces in a table lookup unit (TLU) block (in groups of three). As such, the command displays each route three times. The command does not display any useful output if only RSP is specified or if no location is specified.

Task ID

Task ID

Operations

multicast

read

Usage Guidelines

Use the show mfib hardware route statistics command to display the hardware packet and byte counter for a route. Route counters are kept for (S, G) routes only. A single set of counters is provided for all

(*, G) routes.

This command displays the hardware packet and bytes count on a per-route basis. Per-route hardware counters are kept for (S, G) routes only. However, counters are managed dynamically and allocated on a priority basis and may not be available for each (S, G) route. There is a single set of counters for all

(*, G) routes. For example, interface counters and access list counters have higher priority than route counters.
