Command Purpose
router igrp autonomous-system_number
Enables IGRP routing
network network_number
Specifies the directly connected
network to learn routing information
show ip protocols
Displays the router’s routing
information
show ip route
Displays the IP routing table
debug ip igrp transaction
Displays IGRP transaction
information
debug ip igrp events
Displays a summary of IGRP
transaction information.
undebug all
Disable debugging.
no router igrp autonomous-system_number
Disable IGRP routing process


neighbor ip-address
Because IGRP is normally a
broadcast protocol, in order for IGRP
routing updates to reach nonbroadcast
networks, you must configure the
Cisco IOS software to permit this
exchange of routing information.
This defines a neighboring router
with which to exchange routing
information
timers basic update invalid hold-down flush

Change the default IGRP timers.
show ip route igrp
Display IGRP routes in the routing
table.
