Default

None

Description

This command lets you specify a summary address for routes advertised through a specific interface by EIGRP. This command must be applied only to interfaces. It is beneficial if auto-summary has been disabled for EIGRP, as this allows you to define a specific summary address. This address receives an administrative distance of 5, which is more preferred than regular EIGRP routes.

as-number

The number of the EIGRP routing process.

address

The IP address for the summarized route.

mask

The net mask for the summarized route.
