Cisco Administrative Distances

Submitted by James Gray on October 28, 2009 – 11:25 pmNo Comment

Routing protocols on Cisco routers use administrative distances to determine the best route. If you have multiple routing protocols running on a Cisco router the protocol with the lowest administrative distance will be used. The following is a table that shows the default administrative distances of the protocols.

You can change the default administrative distances of a static route by adding the distance to the end of the ip route command as shown below.
