Overview

BGPv4 is supported as shown in the following table.

For detailed information on configuring BGP, refer to the BGP chapter in the Dell Networking OS

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.
