This command was introduced.


Usage Guidelines

At a minimum interval, VPC vs non-VPC cases, and also with single vs dual sup cases, Basically for vPC and with dual sups one needs to use default timers. the neighbor hold time is automatically set to 3.5x this value. Also it is recommended to use BFD for PIM instead of non-default timers.

This command requires the LAN Base Services license.

Examples

This example shows how to configure the PIM hello-message interval on an interface:

switch(config)# interface ethernet 2/2
switch(config-if)# ip pim hello-interval 20000
 
   

This example shows how to reset the PIM hello-message interval on an interface to the default:

6.0(2)N1(1)

This command was introduced.


Usage Guidelines

The ip pim jp-policy command filters messages in both incoming and outgoing directions. To specify filtering only incoming messages, use the optional in keyword; to specify filtering only outgoing messages, use the optional out keyword. When you enter the command with no keywords, that is no explicit direction, the system rejects further configurations if given with explicit direction.

Use the ip pim jp-policy command to filter incoming messages. You can configure the route map to prevent state from being created in the multicast routing table.

You can specify group, group and source, or group and RP addresses to filter messages with the match ip multicast command.

This command requires the LAN Base Services license.

Examples

This example shows how to filter PIM join-prune messages:

switch(config)# interface ethernet 2/2

Modification

6.0(2)N1(1)

This command was introduced.


Usage Guidelines

To prebuild the SPT for all known (S,G)s in the routing table by triggering PIM joins upstream, even in the absence of any receivers, use the ip pim pre-build-spt command.

By default, PIM (S,G) joins are triggered upstream only if the OIF-list for the (S,G) is not empty. It is useful in certain scenarios—for example, on the virtual port-channel (vPC) nonforwarding router—to prebuild the SPTs and maintain the (S,G) states even when the system is not forwarding on these routes. Prebuilding the SPT ensures faster convergence when a vPC failover occurs.

When you are running virtual port channels (vPCs), enabling this feature causes both vPC peer switches to join the SPT, even though only one vPC peer switch actually routes the multicast traffic into the vPC domain. This behavior results in the multicast traffic passing over two parallel paths from the source to the vPC switch pair, consuming bandwidth on both paths. Additionally, when both vPC peer switches join the SPT, one or more upstream devices in the network may be required to perform additional multicast replications to deliver the traffic on both parallel paths toward the receivers in the vPC domain.

This command requires the LAN Base Services license.

Examples

This example shows how to prebuild the SPT in the absence of receivers:

switch(config)# vrf context Enterprise
switch(config-vrf)# ip pim pre-build-spt
switch(config-vrf)#
