Managing BGP
View BGP activity with the show ip bgp commands. A plain show ip bgp will display every route your router learned via BGP, which includes hundreds of thousands of entries. Most people consider this less than useful. Assorted subcommands break this down into palatable chunks, the most commonly used of which is sho ip bgp summary. The BGP summary is a snapshot of the router's BGP information, including memory usage, routes available, flapping routes, and so on, and ends with a very useful line for each BGP peer. This information is all aggregated from the BGP feed your router receives from each of your providers.
