Chapter 34 Configuring IP Unicast Routing
Configuring Protocol-Independent Features
Note You should configure EIGRP stub routing only on stub routers. A stub router is defined as a router
connected to the network core or distribution layer through which core transit traffic should not flow. A
stub router should not have any EIGRP neighbors other than distribution routers. Ignoring this restriction
will cause undesirable behavior.
For more information about EIGRP stub routing, see “Configuring EIGRP Stub Routing” part of the
Cisco IOS IP Configuration Guide, Volume 2 of 3: Routing Protocols, Release 12.2 from the Cisco.com
page under Documentation > Cisco IOS Software > 12.2 Mainline > Configuration Guides.
Configuring EIGRP Stub Routing
Beginning in privileged EXEC mode, follow these steps to configure a remote or spoke router for EIGRP
stub routing:
Enter the show ip eigrp neighbor detail privileged EXEC command from the distribution router to
verify the configuration.
Configuring Protocol-Independent Features
This section describes how to configure IP routing protocol-independent features. These features are
available on switches running the IP base image or the IP services image; except that with the IP base
image, protocol-related features are available only for RIP. For a complete description of the IP routing
protocol-independent commands in this chapter, see the “IP Routing Protocol-Independent Commands”
chapter of the Cisco IOS IP Command Reference, Volume 2 of 3: Routing Protocols, Release 12.2 from
the Cisco.com page under Documentation > Cisco IOS Software > 12.2 Mainline > Command
References.
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
router eigrp 1 Configure a remote or distribution router to run an EIGRP process and
enter router configuration mode.
Step 3
network network-number Associate networks with an EIGRP routing process.
Step 4
eigrp stub [receive-only | connected |
static | summary]
Configure a remote router as an EIGRP stub router. The keywords have
these meanings:
• Enter receive-only to set the router as a receive-only neighbor.
• Enter connected to advertise connected routes.
• Enter static to advertise static routes.
• Enter summary to advertise summary routes.
Step 5
end Return to privileged EXEC mode.
Step 6
show ip eigrp neighbor detail Verify that a remote router has been configured as a stub router with
EIGRP. The last line of the output shows the stub status of the remote or
spoke router.
Step 7
copy running-config startup-config (Optional) Save your entries in the configuration file.
