The table below describes the significant fields shown in the display.

Table 9show ip pim neighbor Field Descriptions

Field

Description

Neighbor Address

IP address of the PIM neighbor.

Interface

Interface type and number on which the neighbor is reachable.

Uptime

The total uptime of the neighbor (in hours:minutes:seconds).

Expires

The time before a neighbor is timed out and until the next PIM hello is received (in hours:minutes:seconds).

Ver

The version of PIM running on the neighbor's interface.

DR Prio

The priority of the PIM interface for designated router (DR) election. The possible values that can be displayed under this column are as follows: a value from 0 to 4294967294 or the "N" flag. The default DR priority is set to 1.

Note    The DR priority can be modified using the ip pim dr-priority command in interface configuration mode.

When a DR is a candidate for election, the following conditions apply:

  • The router with the highest priority value configured on an interface will be elected as the DR. If this priority value is the same on multiple routers, then the router with the highest IP address configured on an interface will be elected as the DR.
  • If a router does not advertise a priority value in its hello messages, the router is regarded as having the highest priority and will be elected as the DR. If there are multiple routers with this priority status, then the router with the highest IP address configured on an interface will be elected as the DR.

Note    For interoperability, if a PIM neighbor is running a release prior to Cisco IOS Release 12.1(2)T, which does not support the DR priority feature, the "DR Prio" column displays the "N" flag. If the neighbor is the only router displaying the "N" flag for a PIM interface, it becomes the DR regardless of which router actually has the highest IP address. If there are several PIM neighbors with the "N" flag listed under this column, the tiebreaker is the highest IP address among them.

Mode

Information about the DR and other PIM capabilities:

  • B--Indicates that the PIM neighbor is bidirectional PIM (bidir-PIM) capable. In a bidir-PIM network, this capability is necessary for the routers to successfully perform the designated forwarder election process. If a router detects through PIM hello messages that one of its PIM neighbors is not bidir-PIM capable, the designated forwarder election process is aborted and forwarding of bidir-PIM traffic to and from that interface would stop.
  • DR--Indicates that the PIM neighbor is acting as the DR.
  • G--Indicates that the PIM neighbor supports Generation ID (GenID) capabilities, which enable fast PIM multicast route (mroute) reconvergence times after a switchover.
  • P--Indicates that the neighbor has announced through PIM hello messages its capability to handle Reverse Path Forwarding (RPF) vectors in PIM join messages. All Cisco IOS versions that support the PIM RPF Vector feature announce this PIM hello option. An RPF vector is included in PIM messages only when all PIM neighbors on a RPF interface support it.
  • S--Indicates that the PIM neighbor supports PIM-DM state refresh capabilities (applies only to PIM neighbors running in dense mode). This flag was introduced in support of the PIM Dense Mode State Refresh feature. PIM-DM state refresh capabilities protect pruned state in PIM dense mode from timing out by periodically forwarding a control message down the source-based distribution tree. The control message refreshes the prune state on the outgoing interfaces of each router in the distribution tree. By default, all PIM routers that are operating in dense mode (and are running a Cisco IOS software release that supports the PIM Dense Mode State Refresh feature) automatically process and forward state refresh control messages.

12.2SX

This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.

Usage Guidelines

The Protocol Independent Multicast (PIM) version known for an RP influences the type of PIM register messages (Version 1 or Version 2) that the router sends when acting as the designated router (DR) for an active source. If an RP is statically configured, the PIM version of the RP is not set and the router, if required to send register packets, tries to send PIM Version 2 register packets. If sending PIM Version 2 packets fails, the router sends PIM Version 1 register packets.

The version of the RP displayed in the show ip pim rp command output can change according to the operations of the router. When the group is created, the version shown is for the RP in the RP mapping cache. Later, the version displayed by this command may change. If this router is acting as a DR for an active source, the router sends PIM register messages. The PIM register messages are answered by the RP with PIM register stop messages. The router learns from these PIM register stop messages the actual PIM version of the RP. Once the actual PIM version of the RP is learned, this command displays only this version. If the router is not acting as a DR for active sources on this group, then the version shown for the RP of the group does not change. In this case, the PIM version of the RP is irrelevant to the router because the version of the RP influences only the PIM register messages that this router must send.

When you enter the show ip pim rp mapping command, the version of the RP displayed in the output is determined only by the method through which an RP is learned. If the RP is learned from Auto-RP then the RP displayed is either "v1" or "v2, v1." If the RP is learned from a static RP definition, the RP version is undetermined and no RP version is displayed in the output. If the RP is learned from the BSR, the RP version displayed is "v2."

12.2(33)SRE

This command was integrated into Cisco IOS Release 12.2(33)SRE.

Usage Guidelines

Use the show ip pim tunnelcommand to display information about PIM tunnel interfaces.

PIM tunnel interfaces are used by the IPv4 Multicast Forwarding Information Base (MFIB) for the PIM sparse mode (PIM-SM) registration process. Two types of PIM tunnel interfaces are used by the the IPv4 MFIB:

  • A PIM encapsulation tunnel (PIM Encap Tunnel)
  • A PIM decapsulation tunnel (PIM Decap Tunnel).

The PIM Encap Tunnel is dynamically created whenever a group-to-Rendezvous Point (RP) mapping is learned (via Auto-RP, bootstrap router (BSR), or static RP configuration). The PIM Encap Tunnel is used to encapsulate multicast packets sent by first-hop Designated Routers (DRs) that have directly connected sources.

Similar to the PIM Encap Tunnel, the PIM Decap Tunnel interface is dynamically created--with the exception that it is created only on the RP whenever a group-to-RP mapping is learned. The PIM Decap Tunnel interface is used by the RP to decapsulate PIM register messages.


Note


PIM tunnels will not appear in the running configuration.

The following syslog message will appear when a PIM tunnel interface is created:

* %LINEPROTO-5-UPDOWN: Line protocol on Interface Tunnel<interface_number>, changed state to up

Examples

The following is sample output from the show ip pim tunnel command taken from a RP. The output is used to verify the PIM Encap and Decap Tunnel on the RP.

Router# show ip pim tunnel

Usage Guidelines

Use the show ip rpf command to display the information that IP multicast routing uses to perform the Reverse Path Forwarding (RPF) check for a multicast source. When performing the RPF calculation, the router can use multiple routing tables (the unicast routing table, Multiprotocol Border Gateway Protocol (MBGP) table, Distance Vector Multicast Routing Protocol [DVMRP] routing table, or static multicast routes) to determine the interface on which traffic from a source should arrive (the RPF interface). Because the RPF check can be performed from multiple routing tables, the show ip rpfcommand can be used to identify the source of the retrieved information.

In a Multi-Topology Routing (MTR) routing environment, a router can perform RPF lookups from multiple unicast Routing Information Bases (RIBs)--instead of only looking at the original unique unicast RIB. By default, the Cisco IOS software supports the pre-MTR IP multicast behavior; that is, the RPF check is performed on routes in the unicast RIB (base unicast topology).


Note


MTR introduces a multicast topology (base multicast topology) that is completely independent from the unicast topology. MTR integration with multicast allows the path of multicast traffic to be controlled in the network.

Examples

The following is sample output from the show ip rpfcommand:

Router# show ip rpf 172.16.10.13

The following is sample output from the show ip rpf command in an MTR routing environment. In Cisco IOS releases that support MTR, the "RPF topology" field was introduced to indicate which RIB topology is being used for the RPF lookup. For the "RPF topology" field in this example, the first topology listed (ipv4 multicast base) indicates where the nexthop of the RPF lookup is being conducted and the second topology listed (ipv4 unicast data) indicates where the route originated from.

Router# show ip rpf 10.30.30.32
RPF information for ? (10.30.30.32)
  RPF interface: Ethernet1/0
  RPF neighbor: ? (10.1.1.32)

15.0(1)M

This command was integrated into Cisco IOS Release 15.0(1)M.

Usage Guidelines

Use the show ip rpf select command after configuring group-based VRF selection policies to display the configured group-to-VRF mappings. The output displays information about group-based VRF selection policies, including the group address, the VRF mapped to the group where the Reverse Path Forwarding (RPF) lookup is performed, and the name of the access control list (ACL) applied to the policy.

Use the ip multicast rpf select command to configure group-based VRF selection policies. By defining group-based VRF selection policies, you can configure RPF lookups originating in a receiver MVRF or in the global routing table to be resolved in a source MVRF or in the global routing table based on group address.

Examples

The following is sample output from the show ip rpf select command:

Router# show ip rpf select

12.2(33)SXH

This command was integrated into Cisco IOS Release 12.2(33)SXH.

Usage Guidelines

SNMP notifications can be sent as traps or informs. This command enables trap notification requests only.

This command controls (enables or disables) MVRF (ciscoMvpnMvrfChange) trap notifications. A ciscoMvpnMvrfChange trap notification signifies a change about a MVRF in the device. The change event can be the creation of an MVRF, the deletion of an MVRF, or an update on the default or data multicast distribution tree (MDT) configuration of an MVRF. The change event is indicated by the ciscoMvpnGenOperStatusChange object embedded in the trap notification.

MVRF trap notifications are defined by the ciscoMvpnMvrfChange object in the MVPN MIB. When this object is queried from a network management system (NMS) workstation, one of the following values is appended to the object to indicate the configuration state of MVRF trap notifications:

  • true(1)--MVRF trap notifications are enabled.
  • false(2)--MVRF trap notifications are disabled.

The following MVPN MIB tables can be queried to gather details about MVRF change events:

  • ciscoMvpnGenericTable
  • ciscoMvpnMdtDefaultTable
  • ciscoMvpnMdtDataTable

Note


For a complete description of the ciscoMvpnMvrfChange trap notification and MVPN MIB tables, see the CISCO_MVPN_MIB.my file, available on Cisco.com at http://www.cisco.com/go/mibs .

The snmp-server enable traps mvpn command is used in conjunction with the snmp-server host command. Use the snmp-server host command to specify which host or hosts receive SNMP notifications. To send SNMP notifications, you must configure at least one snmp-server host command.

Examples

The following example shows how to enable MVRF traps to the host at IP address 10.3.32.154 using the community string defined as public:

snmp-server enable traps mvpn
snmp-server host 10.3.32.154 version 2c public

snmp-server enable traps pim

To enable Protocol Independent Multicast (PIM) Simple Network Management Protocol (SNMP) notifications, use the snmp-server enable traps pimcommand in global configuration mode. To disable PIM-specific SNMP notifications, use the noform of this command.

snmp-server enable traps pim [neighbor-change | rp-mapping-change | invalid-pim-message]
no snmp-server enable traps pim

Syntax Description

neighbor-change

(Optional) Enables notifications indicating when a router's PIM interface is disabled or enabled, or when a router's PIM neighbor adjacency expires.

rp-mapping-change

(Optional) Enables notifications indicating a change in the rendezvous point (RP) mapping information due to either Auto-RP or bootstrap router (BSR) messages.

invalid-pim-message

(Optional) Enables invalid PIM message traps. For example, an invalid PIM message could result when a router receives a join or prune message for which the RP specified in the packet is not the RP for the multicast group.

Command Default

SNMP notifications are disabled.

12.2SX

This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.

Usage Guidelines

SNMP notifications can be sent as traps or inform requests. This command enables both traps and inform requests for the specified notification types. PIM notifications are defined in the CISCO-PIM-MIB.my and PIM-MIB.my files, available from Cisco.com at http://www.cisco.com/public/sw-center/netmgmt/cmtk/mibs.shtml .

Examples

The following example shows how to configure a router to generate notifications indicating that a PIM interface on the router has been enabled:

! Configure PIM traps to be sent as SNMPv2c traps to host with IP address 10.0.0.1.
Router(config)# snmp-server host 10.0.0.1 traps version 2c public pim
 
! Configure router to send the neighbor-change class of notifications to host.
Router(config)# snmp-server enable traps pim neighbor-change
 
! Enable PIM sparse-dense mode on Ethernet interface 0/0.

Examples

The following example shows how to configure the tunnel udlr address-resolution command on an interface to enable ARP and NHRP over a send-only tunnel. An ARP address resolution request received from the upstream router on the UDL (Ethernet interface 0) will be replied to over the send-only tunnel of the receiver. Likewise, an ARP request may be sent by the downstream router over the send-only tunnel, and the response will be received over the UDL.

Related Commands

Command

Description

tunnel udlr send-only

Configures a unidirectional, GRE tunnel to act as a back channel that can send messages, when another interface is configured for UDLR to receive messages.

tunnel udlr receive-only

To configure a unidirectional, generic routing encapsulation (GRE) tunnel to act as a back channel that can receive messages, when another interface is configured for unidirectional link routing (UDLR) to send messages, use the tunnel udlr receive-onlycommand in interface configuration mode. To remove the tunnel, use the no form of this command.

tunnel udlr receive-only interface-type interface-number
no tunnel udlr receive-only interface-type interface-number

Syntax Description

interface-type interface-number

This command is supported in the Cisco IOS Release 12.2SX train. Support in a specific 12.2SX release of this train depends on your feature set, platform, and platform hardware.

Usage Guidelines

Use this command to configure a router that has a unidirectional interface with send-only capabilities. One example of when you might configure this command is if you have traffic traveling via a satellite.

The interface-type and interface-number arguments must match the send-only interface type and number specified by the interface command.

You must configure the tunnel udlr send-only command at the opposite end of the tunnel.

If you have a large number of receivers, you should configure UDLR by an alternative means: Internet Group Management Protocol (IGMP) UDLR. See the description of the ip igmp unidirectional-link command.

Examples

In the following example, Router A (the upstream router) is configured with Open Shortest Path First (OSPF) and Protocol Independent Multicast (PIM). Serial interface 0 has send-only capability. Therefore, the UDLR tunnel is configured as receive-only, and points to serial interface 0.

Configures a tunnel interface.

ip igmp unidirectional-link

Configures an interface to be unidirectional and enables it for IGMP UDLR.

tunnel udlr send-only

Configures a unidirectional, GRE tunnel to act as a back channel that can send messages, when another interface is configured for UDLR to receive messages.

tunnel udlr send-only

To configure a unidirectional, generic routing encapsulation (GRE) tunnel to act as a back channel that can send messages, when another interface is configured for unidirectional link routing (UDLR) to receive messages, use the tunnel udlr send-onlycommand in interface configuration mode. To remove the tunnel, use the no form of this command.

tunnel udlr send-only interface-type interface-number
no tunnel udlr send-only interface-type interface-number

Syntax Description

interface-type interface-number

Interface type and number. The interface-type and interface-number arguments must match the unidirectional receive-only interface type and number specified by the interface command. Thus, when packets are sent by upper layer protocols over the interface, they will be redirected and sent over this GRE tunnel.

Command Default

No UDLR tunnel is configured.

udp-port

To change the User Datagram Protocol (UDP) port numbers to which a Test Sender sends test packets or a Test Receiver sends status reports during Multicast Routing Monitor (MRM) tests, use the udp-portcommand in MRM manager configuration mode. To restore the default settings, use the no form of this command.

udp-port [test-packet port-number] [status-report port-number]
no udp-port

Syntax Description

test-packet port-number

(Optional) Specifies the UDP port number to which test packets are sent by a Test Sender. The port number must be even if the packets are Real-Time Transport Protocol (RTP)-encapsulated. The range is from 16384 to 65535. By default, the Test Sender uses UDP port number 16834 to send test packets.

status-report port-number

(Optional) Specifies the UDP port number to which status reports are sent by a Test Receiver. The port number must be odd if the packets are RTP Control Protocol (RTCP)-encapsulated. The range is from 16834 to 65535. By default, the Test Receiver uses UDP port number 65535 to send status reports.

Command Default

Test Senders use UDP port number 16834 to send test packets, and Test Receivers use UDP port number 65535 to send status reports.
