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, a 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.
