View
Public instance PIM view, VPN instance PIM view
Default Level
2: System level
Parameters
queue-size: Maximum number of (S, G) entries in a join/prune message, in the range of 1 to 4,096.
Description
Use the jp-queue-size command to configure the maximum number of (S, G) entries in a join/prune
message.
Use the undo jp-queue-size command to restore the system default.
By default, a join/prune messages contains a maximum of 1,020 (S, G) entries.
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 may contain a large number of groups, causing
the message length to exceed the MTU of the network. As a result, the products that do not support
fragmentation will drop the join/prune message.
The (S, G) join/prune timeout time on the upstream device. If you configure a small queue size, the
outgoing interface of the corresponding entry may have been pruned due to timeout before the last
join/prune message in a queue reaches the upstream device.
