jp-queue-size (IPv6 PIM view)
Syntax
jp-queue-size queue-size

View
IPv6 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 4096.
Description
Use jp-queue-size to configure the maximum number of (S, G) entries in a join/prune message.
Use undo jp-queue-size to restore the 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 might contain a large number of groups, which
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 state hold time 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.
