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 inter-domain 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 sent
messages to update those routing tables.
NOTE: For more information about configuring the border gateway protocol (BGP), see the BGP section in the Dell
Networking OS Configuration Guide.
