PIM
Neighbor Filter
The Neighbor Filter pane displays the PIM neighbor filters, if any, that are configured on the security
appliance. A PIM neighbor filter is an ACL that defines the neighbor devices that can participate in PIM.
If a neighbor filter is not configured for an interface, then there are no restrictions. If a PIM neighbor
filter is configured, only those neighbors permitted by the filter list can participate in PIM with the
security appliance.
When a PIM neighbor filter configuration is applied to the security appliance, an ACL appears in the
running configuration with the name interface-name_multicast, where the interface-name is the name of
the interface the multicast boundary filter is applied to. If an ACL with that name already exists, a
number is appended to the name, for example inside_multicast_1. This ACL defines which devices can
become PIM neighbors of the security appliance.
