Monitoring Multicast Routes When OIF Mapping Is Configured
Purpose
Display details of the join interfaces corresponding to the mapped interfaces when OIF mapping is configured.
- You can specify a multicast group IP address or both a multicast group IP address and a multicast source IP address to display information about a particular multicast forwarding entry.
- You can use the active option to display information for the active multicast routes.
- You can specify the bandwidth threshold along with the active option to display information for the active multicast routes with admission bandwidth greater than the specified bandwidth threshold. The default bandwidth threshold is 4000 bps.
Action
To display details of the join interfaces:
host1#show ip mroute oif-detail
IP Multicast Routing Table(S, G) uptime d h:m:s[, expires d h:m:s]
