What command is used to verify PIM neighborship?

To verify PIM (Protocol Independent Multicast) neighborship, the command "show ip pim neighbors" is used. This command provides valuable information about the PIM neighbors that the local router is aware of, including their state, IP addresses, and the interfaces they are connected to. This is crucial for troubleshooting multicast issues and ensuring that routers are correctly forming PIM adjacencies for efficient multicast routing.

The command displays key details including the PIM neighbor's IP address, the hold time, and the interface through which the neighbor is reachable, which can help network operators verify that multicast traffic is being properly forwarded through the network. Understanding the PIM neighborship is essential for ensuring that multicast routing operates as intended, especially in environments where multicast is relied upon for applications like streaming media.

Other commands listed, such as "show ip mroute," focus on the multicast routing table, providing insights into active multicast distributions but not specifically about neighbor relationships. "Show ip multicast-routing" deals with multicast routing protocols but does not provide detailed neighbor status. "Display pim neighbors" is not a valid IOS command; Cisco IOS uses "show" commands for this type of information. Thus, the specific command needed for verifying PIM neighbors is "show ip
