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, the graft retry period—until it receives a graft-ack message from the
upstream router.
Follow these steps to configure the IPv6 PIM-DM graft retry period:
