Fix Recommendation

The router administrator configures and binds a PIM neighbor filter to those interfaces that have PIM enabled.

Check Contents

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.
