IGRP Features
IGRP Commands
• Using router igrp and network
commands to enable IGRP
• Enabling IGRP on an IP-addressed
network
• Monitoring IP packet flow using the show
ip protocol command
• The show ip interfaces command
• The show ip route command
• The debug ip rip command
IGRP Metrics
• Bandwidth – The lowest bandwidth value
in the path
• Delay – The cumulative interface delay
along the path
• Reliability – The reliability on the link
towards the destination as determined by
the exchange of keepalives
• Load – The load on a link towards the
destination based on bits per second
IGRP Routes:
Interior, System, & Exterior
IGRP Stability Features
• Holddowns, Split horizons, & Poison-reverse
updates
Configuring IGRP
Migrating RIP to IGRP
1. Verify existing routing protocol (RIP) on
the routers to be converted.
2. Configure IGRP on RouterA and RouterB
3. Enter show ip protocols on RouterA
and RouterB
4. Enter show ip route on RouterA and
RouterB
Migrating RIP to IGRP
Verifying IGRP Configuration
• Some 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
Troubleshooting IGRP
• The following commands are useful when
troubleshooting IGRP:
– show ip protocols {summary}
– show ip route
– debug ip igrp events IGRP protocol
events
– debug ip igrp transactions IGRP
protocol transactions
– ping
– traceroute
