Chapter 4 Configuring EIGRP
Configuring Basic EIGRP
Use the no feature eigrp command to disable the EIGRP feature and remove all associated
configuration.
Creating an EIGRP Instance
You can create an EIGRP instance and associate an interface with that instance. You assign a unique
autonomous system number for this EIGRP process (see the “Autonomous Systems” section on
page 1-5). Routes are not advertised or accepted from other autonomous systems unless you enable route
redistribution.
BEFORE YOU BEGIN
Ensure that you have enabled the EIGRP feature (see the “Enabling the EIGRP Feature” section on
page 4-9).
EIGRP must be able to obtain a router ID (for example, a configured loopback address) or you must
configure the router ID option.
If you configure an instance tag that does not qualify as an AS number, you must configure the AS
number explicitly or this EIGRP instance will remain in the shutdown state.
