Usage
Information
CAUTION: Dell Force10 recommends that you do not change the administrative distance of
internal routes. Changing the administrative distances may cause routing table
inconsistencies.
The higher the administrative distance assigned to a route means that your confidence in that
route is low. Routes assigned an administrative distance of 255 are not installed in the routing
table.
Routes from confederations are treated as internal BGP routes.
