Configuring IP Unicast Routing
To create an EIGRP routing process, you must enable EIGRP and associate networks. EIGRP sends
updates to the interfaces in the specified networks. If you do not specify an interface network, it is not
advertised in any EIGRP update.
Configuring Basic EIGRP Parameters
Beginning in privileged EXEC mode, follow these steps to configure EIGRP. Configuring the routing
process is required; other steps are optional:
Command
Step 1
configure terminal
Step 2
router eigrp autonomous-system
Step 3
network network-number
Step 4
eigrp log-neighbor-changes
Step 5
metric weights tos k1 k2 k3 k4 k5
Step 6
offset list [access-list number | name] {in | out}
offset [type number]
Step 7
no auto-summary
Step 8
ip summary-address eigrp
autonomous-system-number address mask
Step 9
end
Step 10
show ip protocols
Step 11
copy running-config startup-config
Use the no forms of these commands to disable the feature or return the setting to the default value.

Purpose
Enter global configuration mode.
Enable an EIGRP routing process, and enter router configuration
mode. The AS number identifies the routes to other EIGRP routers
and is used to tag routing information.
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.
(Optional) Adjust the EIGRP metric. Although the defaults have
been carefully set to provide excellent operation in most networks,
you can adjust them.
Caution
Setting metrics is complex and is not recommended
without guidance from an experienced network
designer.
(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.
(Optional) Configure a summary aggregate.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
