Configuring IPv6 PIM-DM graft retry timer
In IPv6 PIM-DM, only the graft process uses the acknowledgment mechanism. After a router sends a graft
message, it starts a graft retry timer. If the router does not receive a graft-ack message from the upstream
router when the timer expires, the router sends another graft message. The router keeps sending graft
messages until it receives a graft-ack message.
For more information about the configuration of other timers in IPv6 PIM-DM, see "Configuring common
PI
M timers."
