Configuring Join/Prune
Message Limits
A larger join/prune message size will result in loss of a larger amount of
information when a message is lost; with a reduced join/message size, the loss of a
single message will bring relatively minor impact.
By controlling the maximum number of (S, G) entries in a join/prune message, you
can effectively reduce the number of (S, G) entries sent per unit of time.
Follow these steps to configure join/prune message limits:
