Configuring EIGRP Stub Routing
The EIGRP stub routing feature, available in all images, reduces resource utilization by moving routed
traffic closer to the end user.
traffic closer to the end user.
Note
The IP base image contains only EIGRP stub routing capability, which only advertises connected or
summary routes from the routing tables to other switches in the network. The switch uses EIGRP stub
routing at the access layer to eliminate the need for other types of routing advertisements. For enhanced
capability and complete EIGRP routing, the switch must be running the IP services image.

On a switch running the IP base image, if you try to configure multi-VRF-CE and EIGRP stub routing
at the same time, the configuration is not allowed.

In a network using EIGRP stub routing, the only allowable route for IP traffic to the user is through a
switch that is configured with EIGRP stub routing. The switch sends the routed traffic to interfaces that
are configured as user interfaces or are connected to other devices.

When using EIGRP stub routing, you need to configure the distribution and remote routers to use EIGRP
and to configure only the switch as a stub. Only specified routes are propagated from the switch. The
switch responds to all queries for summaries, connected routes, and routing updates.

Any neighbor that receives a packet informing it of the stub status does not query the stub router for any
routes, and a router that has a stub peer does not query that peer. The stub router depends on the
distribution router to send the proper updates to all peers.
