Implementing Multiprotocol BGP for IPv6

First Published: May 5, 2008
Last Updated: July 30, 2010

This module describes how to configure multiprotocol Border Gateway Protocol (BGP) for IPv6. BGP
is an Exterior Gateway Protocol (EGP) used mainly to connect separate routing domains that contain
independent routing policies (autonomous systems). Connecting to a service provider for access to the Internet is a common use for BGP. BGP can also be used within an autonomous system and this variation is referred to as internal BGP (iBGP). Multiprotocol BGP is an enhanced BGP that carries routing information for multiple network layer protocol address families, for example, IPv6 address family and for IP multicast routes. All BGP commands and routing policy capabilities can be used with
multiprotocol BGP.
