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.
IPv6 border gateway protocol (IPv6 BGP) is an extension of the external gateway protocol that transmits
interdomain routing information with extended IP address space within and between autonomous
systems (AS).
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:
• BGPv4 Commands
• MBGP Commands
• BGP Extended Communities (RFC 4360)
• IPv6 BGP Commands
