BGPv4 Commands

Border Gateway Protocol (BGP) is an external gateway protocol that transmits interdomain

routing information within and between Autonomous Systems (AS). BGP version 4 (BGPv4)

supports Classless InterDomain Routing (CIDR) and the aggregation of routes and AS paths.

Basically, two routers (called neighbors or peers) exchange information including full routing

tables and periodically send messages to update those routing tables.
