IPv6 PIM Sparse 4
Syntax: rp-adv-interval seconds
The seconds parameter specifies the number of seconds in a range from 10 through 65535. The
default is 60 seconds.
Changing the PIM Join and Prune message interval
By default, the device sends PIM Sparse Join or Prune messages every 60 seconds. These
messages inform other PIM Sparse routers about clients who want to become receivers (Join) or
stop being receivers (Prune) for PIM Sparse groups.
NOTE
Use the same Join or Prune message interval on all the PIM Sparse routers in the PIM Sparse
domain. If the routers do not all use the same timer interval, the performance of PIM Sparse can be
adversely affected.
To change the Join or Prune interval, enter commands such as the following.
Brocade(config)# ipv6 router pim
Brocade(config-ipv6-pim-router)# message-interval 30
To change the Join or Prune interval for a specified VRF, enter the commands as shown in the
following example.
Brocade(config)# ipv6 router pim vrf blue
Brocade(config-ipv6-pim-router-vrf-blue)# message-interval 30
Syntax: [no] message-interval seconds
The seconds parameter specifies the number of seconds and can be from 10 through 65535
seconds. The default is 60 seconds.
Modifying neighbor timeout
Neighbor timeout is the interval after which a PIM router will consider a neighbor to be absent. If
the timer expires before receiving a new hello message, the PIM router will time out the neighbor.
To apply an IPv6 PIM neighbor timeout value of 50 seconds to all ports on the router operating with
PIM, enter the commands such as the following.
Brocade(config)# ipv6 router pim
Brocade(config-ipv6-pim-router)# nbr-timeout 50
To apply an IPv6 PIM neighbor timeout value of 50 seconds for a specified VRF operating with PIM,
enter the commands such as the following.
Brocade(config)# ipv6 router pim vrf blue
Brocade(config-ipv6-pim-router-vrf-blue)# nbr-timeout 50
Syntax: [no] nbr-timeout seconds
The seconds parameter specifies the number of seconds. The valid range is from 35 through
65535 seconds. The default is 105.
Setting the prune wait interval
The prune-wait command allows you to set the amount of time the PIM router should wait for a join
override before pruning an Outgoing Interface List Optimization (OIF) from the entry.
