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 "Configuring multicast routing and forwarding." 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).
