BGP – Prefix aggregation using a static route
My previous post on BGP prefix aggregation used the bgp “aggregate-address” command. Another way to generate an aggregate is by using a static route.
Consider the toplology below.
Watch the video below to see how to configure a BGP aggregate using a static route. Alternatively down the video here and watch it on your iPod.
The commands used in the above video are listed below.
