Configuring IPv6 PIM-DM Graft Retry Period
In IPv6 PIM-DM, graft is the only type of message that uses the acknowledgment mechanism. In an
IPv6 PIM-DM domain, if a router does not receive a graft-ack message from the upstream router within
the specified time after it sends a graft message, the router keeps sending new graft messages at a
configurable interval, namely graft retry period, until it receives a graft-ack from the upstream router.
