7.3 IGRP  
  7.3.7 Verifying IGRP configuration  
To verify that IGRP has been configured properly, enter the show ip route command and look for IGRP routes signified by an "I".

Additional commands for checking IGRP configuration are as follows:

  • show interface interface
  • show running-config
  • show running-config interface interface
  • show running-config | begin interface interface
  • show running-config | begin igrp
  • show ip protocols

To verify that the Ethernet interface is properly configured, enter the show interface fa0/0 command. Figure illustrates the output.

To see if IGRP is enabled on the router, enter the show ip protocols command. Figure illustrates the output.

The commands illustrated in Figures verify the network statements, IP addressing, and routing tables.
