Command Line Interface
Command Usage
The multicast interface that first receives a multicast stream from a particular
source forwards this traffic to all other PIM interfaces on the router. If there are
no requesting groups on that interface, the leaf node sends a prune message
upstream and enters a prune state for this multicast stream. The prune state is
maintained until the join-prune-holdtime timer expires or a graft message is
received for the forwarding entry.
Example
Console(config-if)#ip pim join-prune-holdtime 60
Console(config-if)#
ip pim graft-retry-interval
This command configures the time to wait for a Graft acknowledgement before
resending a Graft. Use the no form to restore the default value.
Syntax
ip pim graft-retry-interval seconds
no ip pim graft-retry-interval
seconds - The time before resending a Graft. (Range: 0-65535)
Default Setting
3 seconds
Command Mode
Interface Configuration (VLAN)
Command Usage
A graft message is sent by a router to cancel a prune state. When a router
receives a graft message, it must respond with an graft acknowledgement
message. If this acknowledgement message is lost, the router that sent the
graft message will resend it a number of times (as defined by the ip pim
max-graft-retries command).
Example
Console(config-if)#ip pim graft-retry-interval 9
Console(config-if)#
ip pim max-graft-retries
This command configures the maximum number of times to resend a Graft message
if it has not been acknowledged. Use the no form to restore the default value.
Syntax
ip pim max-graft-retries retries
no ip pim graft-retry-interval
retries - The maximum number of times to resend a Graft.
