8 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 Topics: • BGP IPv4 Commands • MBGP Commands • BGP Extended Communities (RFC 4360) • IPv6 BGP Commands • IPv6 MBGP Commands BGP IPv4 Commands Border Gateway Protocol (BGP) is an external gateway protocol that transmits interdomain routing information within and between Autonomous Systems (AS).

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:
