Configuring PIM-DM Graft Retry Period
In PIM-DM, graft is the only type of message that uses the acknowledgment mechanism. In a
PIM-DM domain, if a router does not receive a graft-ack message from the upstream router

messages at a configurable interval, namely graft retry period, until it receives a graft-ack from
the upstream router.
