Chapter 32 Configuring IP Unicast Routing
Configuring EIGRP
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:
Use the no forms of these commands to disable the feature or return the setting to the default value.
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
router eigrp autonomous-system 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.
Step 3
network network-number Associate networks with an EIGRP routing process. EIGRP sends
updates to the interfaces in the specified networks.
Step 4
eigrp log-neighbor-changes (Optional) Enable logging of EIGRP neighbor changes to monitor
routing system stability.
Step 5
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.
Caution Setting metrics is complex and is not recommended
without guidance from an experienced network
designer.
Step 6
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.
Step 7
no auto-summary (Optional) Disable automatic summarization of subnet routes into
network-level routes.
Step 8
ip summary-address eigrp
autonomous-system-number address mask
(Optional) Configure a summary aggregate.
Step 9
end Return to privileged EXEC mode.
Step 10
show ip protocols Verify your entries.
Step 11
copy running-config startup-config (Optional) Save your entries in the configuration file.
