Configuring IPv6 PIM-DM graft retry timer
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 (graft retry timer) until it receives a graft-ack message from the upstream router. For
more information about the configuration of other timers in IPv6 PIM-DM, see "Configuring common IPv6
PI
M timers."
