Configuring join/prune message sizes
A large size of a join/prune message might result in loss of a larger amount of information if a message
is lost. You can set a small value for the size of each join/prune message to reduce the impact in case of
the loss of a message.
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.
IMPORTANT:
If PIM snooping–enabled switches are deployed in the PIM network, be sure to set a value no
g
reater than
the path MTU for the maximum size of each join/prune message on the receiver-side edge PIM devices
