Blade ICE RACKSWITCH G8124-E Manuale Utente

BMD00220, October 2010

Chapter 21: Protocol Independent Multicast

The G8124 accepts connection to up to 72 PIM interfaces. By default, the switch accepts all PIM 
neighbors attached to the PIM-enabled interfaces, up to the maximum number. Once the maximum 
is reached, the switch will deny further PIM neighbors.

To ensure that only the appropriate PIM neighbors are accepted by the switch, the administrator can 
use PIM neighbor filters to specify which PIM neighbors may be accepted or denied on a 
per-interface basis.

To turn PIM neighbor filtering on or off for a particular IP interface, use the following commands:

When filtering is enabled, all PIM neighbor requests on the specified IP interface will be denied by 
default. To allow a specific PIM neighbor, use the following command:

To remove a PIM neighbor from the accepted list, use the following command.

You can view configured PIM neighbor filters globally or for a specific IP interface using the 
following commands:

RS G8124(config)# interface ip

RS G8124(config-ip-if)# [no] ip pim neighbor-filter

RS G8124(config-ip-if)# ip pim neighbor-addr

RS G8124(config-ip-if)# ip pim neighbor-addr

RS G8124(config-ip-if)# exit

RS G8124(config)# show ip pim neighbor-filters

RS G8124(config)# show ip pim interface
