Configuring IPv6 PIM on a port or VLAN

Configure PIM for each interface to enable the interface to perform multicasting operations.

Before you begin

Enter Interface Configuration mode:

enable

configure terminal

interface GigabitEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...]} or interface vlan <1–4059>

Note

If the platform supports channelization and the port is channelized, you must also specify the sub-port in the format slot/port/sub-port.
Create a PIM interface on a port or VLAN:

ipv6 pim enable

This command creates an active interface, by default.
Configure the interval for join and prune messages:

ipv6 pim join-prune-interval <1–18724>
Configure the time between hello messages:

ipv6 pim hello-interval <0–18724>

Switch:1(config-if)#ipv6 pim join-prune-interval 60
Switch:1(config-if)#ipv6 pim hello-interval 30

The following table describes the variables for the ipv6 pim command.

Variable	Description
hello-interval <0-18724>	Specifies the duration in seconds before the PIM router sends out the next hello message to neighboring switches. The default value is 30 seconds.
join-prune-interval <1-18724>	Specifies the duration in seconds before the PIM router sends out the next join or prune message to its upstream neighbors. The default value is 60 seconds.
