Configuring IPv6 MBGP configuration
This chapter describes only configuration for IPv6 MBGP. For IPv6 BGP related information, see Layer
3—IP Routing Configuration Guide.
BGP-4 can carry routing information for IPv4 only. IETF defined multi-protocol BGP extensions to carry
routing information for multiple network layer protocols.
On an IPv6 network, the IPv6 multicast topology must be different from the IPv6 unicast topology. To meet
the requirement, the multi-protocol BGP extensions enable IPv6 BGP to carry the IPv6 unicast NLRI and
IPv6 multicast NLRI separately, and the multicast NLRI performs RPF exclusively. In this way, route
selection for a destination through the IPv6 unicast routing table and through the IPv6 multicast routing
table will have different results, ensuring the normal unicast and multicast operation across ASs.
Multi-protocol BGP is defined in RFC 2858 (Multiprotocol Extensions for BGP-4).
Multi-protocol BGP for IPv6 multicast is referred to as IPv6 multicast BGP (IPv6 MBGP). This document
covers configuration tasks related to multi-protocol BGP for IPv6 multicast only. For BGP related
information, see
For information about RPF, see
Configuring IPv6 MBGP basic functions
Prerequisites
IPv6 MBGP is an application of multi-protocol BGP. Before configuring IPv6 MBGP, complete the
following:
•
Enable IPv6
•
Configure network layer addresses for interfaces
•
Complete BGP basic configuration
