BGP4+ Overview

The SLX-OS device supports IPv6 multiprotocol BGP (MBGP) extensions that allow Border Gateway Protocol version 4 plus (BGP4+) to distribute routing information.

BGP4+ supports the same features and functionality as IPv4 BGP (BGP4). For more information, see BGP4 Overview.

IPv6 MBGP enhancements include:

• An IPv6 unicast address family and network layer reachability information (NLRI)
• Next hop attributes that use IPv6 addresses

Note

BGP4+ supports the advertising of BGP4+ unicast routes among different address families. It does not support BGP4+ multicast routes.
