Hands-on Lab 5.3: Dynamic Routing with IGRP
In this lab, you will run the IGRP routing protocol simultaneously with RIP
routing.
1.
Log into your routers and go into privileged mode by typing en or
enable
.
2.
Keep RIP running on your routers and verify that it is running on each
router. If you want to remove RIP, you can use the no router rip
global configuration command to remove it from each router. For
example,
config t
no router rip
3.
From the configuration mode on Router 2501A, type router igrp ?.
4.
Notice that it asks for an autonomous system number. This is used to
allow only routers with the same AS number to communicate. Type 10
and press Enter. Your router can be configured to be part of as many
different ASs as necessary.
5.
At the config-router prompt, type network 172.16.0.0. Notice that
we add the classful network boundary to advertise, rather than the
subnet numbers.
6.
Press Ctrl
+Z to get out of configuration mode.
7.
Go to Routers 2501B and 2501C as well as the 2621A router and type
the commands shown here:
2501B(config)#router igrp 10
2501B(config-router)#network 172.16.0.0
8.
Verify that IGRP is running by typing the following command at each
router:
show ip protocol
