PIM-DM COMMANDS

PIM MAX-GRAFT-RETRIES
ip pim max-graft-retries
Overview This command configures PIM-DM to send a limited number of Graft message
retries, after which time the device will remove all information regarding the
particular (Source, Group), or until the device receives an acknowledgment,
whichever occurs first.
The no variant of this command configures PIM-DM to send Graft message retries
until the device receives an acknowledgment, which is the default behavior.
Syntax
ip pim max-graft-retries <1-65535>
no pim max-graft-retries
Default By default, Graft retries are sent by PIM-DM until the device receives an
acknowledgment.
Mode Interface Configuration for a VLAN interface.
Usage Graft messages are used to reduce the join latency when a previously pruned
branch of the source tree must be grafted back, when a member joins the group
after the PIM-DM device has sent a Prune message to prune unwanted traffic. Graft
messages are the only PIM-DM messages that receive an acknowledgment.
If Graft messages were not used, then the member waiting for pruned off traffic
would have to wait up to 3 minutes for the periodic re-flooding to occur to begin
receiving multicast traffic again. By using Grafts, the Prune can be reversed much
faster than waiting for periodic re-flooding to begin receiving multicast traffic
again.
Examples To configure PIM-DM on the VLAN interface vlan2 to send a maximum of 10 Graft
message retries, use the following commands:
awplus# configure terminal
awplus(config)# interface vlan2
awplus(config-if)# ip pim max-graft-retries 10
