EIGRP Routing Policy Page
EIGRP Page—Interfaces Tab
Use the EIGRP Interfaces tab to create, edit, and delete interface properties for selected EIGRP
autonomous systems. This includes modifying the default hello interval and disabling split horizon.
Note You can access the EIGRP Interfaces tab only after defining at least one EIGRP autonomous system in
the Setup tab. See EIGRP Page—Setup Tab, page 64-13.
Navigation Path
Go to the EIGRP Routing Policy Page, page 64-13, then click the Interfaces tab.

Field Reference
Networks The networks associated with the EIGRP route. Enter one or more
network addresses or network/host objects, separated by commas.
Click Select to select network/host objects from a list of existing
objects, or to create new objects.
Passive Interfaces The interfaces that do not send updates to their routing neighbors. Enter
one or more interface names or roles, separated by commas. Click
Select to select interface names or roles from a list of existing objects,
or to create new interface role objects.
Note When you make an interface passive, EIGRP suppresses the
exchange of hello packets between routers, resulting in the loss
of their neighbor relationship. This not only stops routing
updates from being advertised but also suppresses incoming
routing updates.
Auto-Summary When selected, enables the automatic summarization of subnet routes
into network-level routes. Summarization reduces the size of routing
tables, thereby reducing the complexity of the network.
When deselected, automatic summarization is disabled.
