`Router(config)#router igrpas-number`	Enables IGRP routing process. The autonomous system number (AS-number) used in the IGRP routing process must match all other routers that are going to share routing updates in order for communication to take place
`Router(config-router)#network` `w.x.y.z`	w.x.y.z is the network number of the directly connected network you want to advertise

Note:

You need to advertise only the classful network number, not a subnet:

Router(config-router)#network 172.16.0.0

not

Router(config-router)#network 172.16.10.0

If you advertise a subnet, you will not receive an error message, because the router will automatically convert the subnet to the classful network address.
