Configuring IPv6 MBGP

This chapter covers configuration tasks related to multiprotocol BGP for IPv6 multicast. For information
about BGP and IPv6 BGP, see Layer 3—IP Routing Configuration Guide.
The term "router" in this chapter refers to both routers and Layer 3 switches.

IPv6 MBGP overview

IETF defined Multiprotocol BGP (MP-BGP) to carry routing information for multiple network-layer
protocols.
For an IPv6 network, the topology for IPv6 multicast might be different from that for IPv6 unicast. To
distinguish them, the MP-BGP enables BGP to carry the IPv6 unicast Network Layer Reachability
Information (NLRI) and IPv6 multicast NLRI separately, and the multicast NLRI performs reverse path
forwarding (RPF) exclusively. In this way, route selection for a destination through the IPv6 unicast routing
table and through the IPv6 multicast routing table have different results, ensuring consistent unicast
forwarding and normal multicast between domains. For information about RPF, see
multicast routing and
MP-BGP is defined in RFC 2858 (Multiprotocol Extensions for BGP-4). The application of MP-BGP on IPv6
multicast is called IPv6 Multicast BGP (IPv6 MBGP).
