PIM Dense

Enabling PIM for a specified VRF
To enable PIM for the VRF named “blue”, use the following commands.
Brocade(config)# router pim vrf blue
Syntax: [no] router pim [vrf vrf-name]
The vrf parameter allows you to configure PIM (PIM-DM and PIM-SM) on the virtual routing instance
(VRF) specified by the vrf-name variable. All PIM parameters available for the default device
instance are configurable for a VRF-based PIM instance.
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.
Brocade(config)# router pim
Brocade(config)# int e 1/3
Brocade(config-if-e10000-1/3)# ip address 207.95.5.1/24
Brocade(config-if-e10000-1/3)# ip pim
Brocade(config-if-e10000-1/3)# write memory
Brocade(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.
Brocade(config-if-e10000-1/1)# ip pim version 2
Brocade(config-if-e10000-1/1)# no ip pim version 1
To disable PIM DM on the interface, enter the following command.
Brocade(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.
