queue-size: Specifies the maximum number of (S, G) entries in each join/prune message, in the range of
1 to 4096.
Usage guidelines
When you use this command, take the following into account:
• The size of the forwarding table. In a network that does not support packet fragmentation, if you
configure a large queue size, each join/prune message might contain a large number of groups.
This might cause the message length to exceed the MTU of the network. As a result, the products
that do not support fragmentation drop the join/prune message.
• The (S, G) join/prune timeout timer on the upstream device. If you configure a small queue size, the
outgoing interface of the corresponding entry might have been pruned because of timeout before
the last join/prune message in a queue reaches the upstream device.
Examples
# Configure each join/prune message to contain a maximum of 2000 (S, G) entries.
