Configuring PIM-DM graft retry timer
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 within the specified
time after it sends a graft message, the router keeps sending new graft messages at a configurable
interval known as graft retry timer, until it receives a graft-ack message from the upstream router. For more
information about the configuration of other timers in PIM-DM, see
To configure the graft retry timer:

1.
Enter system view.
2.

interoperable at the network layer.
