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