Displaying System and Network Statistics
You can display specific statistics, such as the contents of IP routing tables and databases. Information
provided can be used to determine resource utilization and solve network problems. You can also display
information about node reachability and discover the routing path your device’s packets are taking using
the network.
To display various routing statistics, enter any of these commands:
Displaying the Multicast Routing Table
The following is sample output from the show ip mroute command for a router operating in dense mode.
This command displays the contents of the IP multicast FIB table for the multicast group named
cbone-audio.
Switch# show ip mroute cbone-audio
