Check Text ( C-39167r1_chk )
Review the router or multi-layer switch to determine if either IPv4 or IPv6 multicast routing is enabled. If either is enabled, verify that all interfaces enabled for PIM has a neighbor filter to only accept PIM control plane traffic from the documented routers according to the multicast topology diagram.

Fix Text (F-34301r1_fix)
If IPv4 or IPv6 multicast routing is enabled, ensure that all interfaces enabled for PIM has a neighbor filter to only accept PIM control plane traffic from the documented routers according to the multicast topology diagram.
