Default Level

2: Configuration level

Usage Guidelines

By default, the size is 8100 bytes.

If the peer device has low performance and takes a long time to process a single Join/Prune message carrying a lot of (S, G) entries, the maximum size of each Join/Prune message can be set to a small value to limit the number of (S, G) entries in each message, relieving the burden on the peer device.

If the maximum size specified in the join-prune max-packet-length command is greater than the interface MTU, the maximum size of each message to be sent is equal to the interface MTU.

Example

# Set the maximum size of each Join/Prune message to be sent to 2100 bytes.
