Border Gateway Protocol IPv4 (BGPv4)

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.

Dell Networking OS supports BGPv4 on the S5000 switch:

NOTE: For more information about configuring the border gateway protocol (BGP), refer to the BGP

chapter in the Dell Networking OS Configuration Guide.

This chapter contains the following sections:
