Changing The Pim Join And Prune Message Interval; Mll Optimization; Statistics - Dell PowerConnect B-RX Configuration Manual

The infinity | <num> parameter specifies the number of packets. If you specify infinity, the BigIron
RX sends packets using the RP indefinitely and does not switch over to the SPT. If you enter a
specific number of packets, the BigIron RX does not switch over to using the SPT until it has sent
the number of packets you specify using the RP.

Changing the PIM join and prune message interval

By default, the BigIron RX sends PIM Sparse Join/Prune messages every 60 seconds. These
messages inform other PIM Sparse routers about clients who want to become receivers (Join) or
stop being receivers (Prune) for PIM Sparse groups.
NOTE
Use the same Join/Prune message interval on all the PIM Sparse routers in the PIM Sparse domain.
If the routers do not all use the same timer interval, the performance of PIM Sparse can be adversely
affected.
To change the Join/Prune interval, enter commands such as the following.
BigIron RX(config)# router pim
BigIron RX(config-pim-router)# message-interval 30
Syntax: [no] message-interval <num>
The <num> parameter specifies the number of seconds and can from 1 – 65535. The default is
60.

MLL optimization

MLL optimization is enabled by default, except for trunks in order that trunk load sharing remains
unaffected. The ip multicast-routing optimization oif-list trunks command can be used to turn on
optimization for trunks such that the degree of 'even balance' may be less than when not
optimized.
BigIron RX(config)# ip multicast-routing optimization oif-list trunks
Syntax: ip multicast-routing optimization oif-list trunks
