Modifying graft retransmit timer
The Graft Retransmit Timer defines the interval between the transmission of graft messages.
A graft message is sent by a router to cancel a prune state. When a router receives a graft
message, the router responds with a Graft Ack (acknowledge) message. If this Graft Ack message
is lost, the router that sent the graft message will resend it.
To change the graft retransmit timer from the default of 180 to 90 seconds, enter the following.
BigIron RX(config)# router pim
BigIron RX(config-pim-router)# graft-retransmit-timer 90
Syntax: graft-retransmit-timer <60-3600>
The default is 180 seconds.
Modifying inactivity timer
The router deletes a forwarding entry if the entry is not used to send multicast packets. The PIM
inactivity timer defines how long a forwarding entry can remain unused before the router deletes it.
To apply a PIM inactivity timer of 90 seconds to all PIM interfaces, enter the following.
BigIron RX(config)# router pim
BigIron RX(config-pim-router)# inactivity-timer 90
Syntax: inactivity-timer <10-3600>
The default is 180 seconds.
