Description |

Protocol Independent Multicast (PIM) is a routing protocol used to build multicast distribution tress for forwarding multicast traffic across the network infrastructure. 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. |

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. |
