The [no] router pim vrf command behaves in the following manner:

•

Entering the router pim vrf command to enable PIM does not require a software reload.

•

Entering a no router pim vrf command removes all configuration for PIM multicast on the
specified VRF.

Enabling a PIM version

To enable PIM on an interface, globally enable PIM, then enable PIM on interface 3, enter the
following commands.

Device(config)# router pim

Device(config)# int e 1/3

Device(config-if-e10000-1/3)# ip address 207.95.5.1/24

Device(config-if-e10000-1/3)# ip pim

Device(config-if-e10000-1/3)# write memory

Device(config-if-e10000-1/3)# end

Syntax: [no] ip pim [version 1 | 2 ]

The version 1 | 2 parameter specifies the PIM DM version. The default version is 2.

If you have enabled PIM version 1 but need to enable version 2 instead, enter either of the following
commands at the configuration level for the interface.

Device(config-if-e10000-1/1)# ip pim version 2

Device(config-if-e10000-1/1)# no ip pim version 1

To disable PIM DM on the interface, enter the following command.

Device(config-if-e10000-1/1)# no ip pim

Modifying PIM global parameters

PIM global parameters come with preset values. The defaults work well in most networks, but you can
modify the following parameters if necessary:

•

Neighbor timeout

•

Hello timer

•

Prune timer

•

Prune wait timer

•

Graft retransmit timer

•

Inactivity timer

Modifying neighbor timeout

Neighbor timeout is the interval after which a PIM device will consider a neighbor to be absent.
Absence of PIM hello messages from a neighboring device indicates that a neighbor is not present.

The interval can be set between 3 and 65535 seconds, and it should not be less than 3.5 times the
hello timer value. The default value is 105 seconds.

To apply a PIM neighbor timeout value of 360 seconds to all ports on the device operating with PIM,
enter the following.

Device(config)# router pim

Device(config-pim-router)# nbr-timeout 360

Syntax: [no] nbr-timeout seconds
