If you have routers on your network that are configured for IGRP, and you want to change to EIGRP, you 
must designate transition routers that have both IGRP and EIGRP configured. In these cases, perform 
Steps 1 through 3 in the next section and also see the 

. 

You must use the same AS number for routes to be automatically redistributed.

The EIGRP NSF Awareness feature is supported for IPv4 in the IP services image. When the neighboring 
router is NSF-capable, the Layer 3 switch continues to forward packets from the neighboring router 
during the interval between the primary Route Processor (RP) in a router failing and the backup RP 
taking over, or while the primary RP is manually reloaded for a nondisruptive software upgrade. 

This feature cannot be disabled. For more information on this feature, see the EIGRP Nonstop 
Forwarding (NSF) Awareness Feature Guide at this URL: 

Beginning in privileged EXEC mode, follow these steps to configure EIGRP. Configuring the routing 
process is required; other steps are optional:

Enter global configuration mode.

router eigrp autonomous-system number

Enable an EIGRP routing process, and enter router configuration 
mode. The AS number identifies the routes to other EIGRP routers 
and tags routing information.

network network-number

Associate networks with an EIGRP routing process. EIGRP sends 
updates to the interfaces in the specified networks. 

(Optional) Enable logging of EIGRP neighbor changes to monitor 
routing system stability.

metric weights tos k1 k2 k3 k4 k5 

(Optional) Adjust the EIGRP metric. Although the defaults have 
been carefully set to provide excellent operation in most networks, 
you can adjust them.

Setting metrics is complex and is not recommended 
without guidance from an experienced network 
designer.

offset list [access-list number | name] {in | out} 
offset [type number]

(Optional) Apply an offset list to routing metrics to increase 
incoming and outgoing metrics to routes learned through EIGRP. 
You can limit the offset list with an access list or an interface.

(Optional) Disable automatic summarization of subnet routes into 
network-level routes.

autonomous-system-number address mask

(Optional) Configure a summary aggregate.
