PIM Neighbor Filters
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 <Interface number>
RS G8124(config-ip-if)# [no] ip pim neighbor-filter
RS G8124(config-ip-if)# ip pim neighbor-addr <neighbor IPv4 address> allow
RS G8124(config-ip-if)# ip pim neighbor-addr <neighbor IPv4 address> deny
RS G8124(config-ip-if)# exit
RS G8124(config)# show ip pim neighbor-filters
RS G8124(config)# show ip pim interface <Interface number> neighbor-filters
