Enabling PIM for IPv6 on an Interface

You can enable PIM on an interface in one of the allowed modes and specify how often the interface sends hello messages to neighbors.

You can configure PIM and MLD on the same interface. If you configure MLD and PIM on an interface, the router considers that PIM owns the interface.

To enable PIM on an interface:

  1. Enable PIM in sparse mode on an interface.
    host1(config-if)#ipv6 pim sparse-mode

    Use the no version to disable PIM in sparse mode on an interface.

  2. Specify the interval, in seconds, at which the router sends hello messages to neighbors.
    host1(config-if)#ipv6 pim query-interval 100

    Use the no version to restore the default setting, 30 seconds.

  3. Set the graceful restart duration for IP PIM sparse mode.
    host1(config-if)#ip pimv6 sparse-mode graceful-restart-duration 10

    Use the no version to return to the default duration of 30 seconds.
