Monitoring and Maintaining BGP

You can remove all contents of a particular cache, table, or database. This might be necessary when the
contents of the particular structure have become or are suspected to be invalid.
You can display specific statistics, such as the contents of BGP routing tables, caches, and databases.
You can use the information to get resource utilization and solve network problems. You can also display
information about node reachability and discover the routing path your device's packets are taking
through the network.
