A network administrator is troubleshooting an IP multicast problem. Where can the administrator view source S, group G, incoming interfaces (IIF), outgoing interfaces (OIFs), and RPF neighbor information for each multicast route?
- in unicast routing table
- in the multicast forwarding information base
- in the multicast routing information base
- in the routing information base
Answers Explanation & Hints:
The multicast routing information base (MRIB) is a topology table that is also known as the multicast route table (mroute). The MRIB is built using PIM and the routing table. It contains the source S, group G, incoming interfaces (IIF), outgoing interfaces (OIFs), and RPF neighbor information for each multicast route as well as other multicast-related information. The command show ip mroute is used to display the full contents of the IP multicast routing table. |
