| Description | ||||
| Protocol Independent Multicast (PIM) is a routing protocol that is used by the IP core for forwarding multicast traffic. PIM traffic must be limited to only known PIM neighbors by configuring and binding a PIM neighbor filter to those interfaces that have PIM enabled. | ||||

Check Text (C-251389r806122_chk)
Step 1: Verify that an ACL is configured that will specify the allowable PIM neighbors similar to the following example.
ip access-list standard pim-neighbors permit 192.0.2.1
permit 192.0.2.3
Step 2: Verify that a pim neighbor-filter command is configured on all PIM enabled interfaces that is referencing the PIM neighbor ACL similar to the following example:
interface GigabitEthernet0/3
ip address 192.0.2.2 255.255.255.0
pim neighbor-filter pim-neighbors
If PIM neighbor filter is not bound to interfaces that have PIM enabled, this is a finding.
Fix Text (F-54777r806121_fix)
The router administrator configures and binds a PIM neighbor filter to those interfaces that have PIM enabled.
