• Entering router pim command to enable PIM does not require a software reload.
• Entering a no router pim command removes all configuration for PIM multicast on a BigIron RX
(router pim level) only.
Enabling a PIM version
To enable PIM on an interface, globally enable PIM, then enable PIM on interface 1/3, enter the
following commands.
BigIron RX(config)# router pim
BigIron RX(config)# int e 1/3
BigIron RX(config-if-e10000-1/3)# ip address 207.95.5.1/24
BigIron RX(config-if-e10000-1/3)# ip pim
BigIron RX(config-if-e10000-1/3)# write memory
BigIron RX(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.
BigIron RX(config-if-e10000-1/1)# ip pim version 2
BigIron RX(config-if-e10000-1/1)# no ip pim version 1
To disable PIM DM on the interface, enter the following command.
BigIron RX(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 you need to:
• 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 router will consider a neighbor to be absent.
Absence of PIM hello messages from a neighboring router indicates that a neighbor is not present.
The default value is 180 seconds.
To apply a PIM neighbor timeout value of 360 seconds to all ports on the router operating with PIM,
enter the following.
BigIron RX(config)# router pim
BigIron RX(config-pim-router)# nbr-timeout 360
Syntax: nbr-timeout <60-8000>
The default is 180 seconds.
