IPv6 BGP

The term "router" in this document refers to both routers and routing-capable firewalls and firewall

modules.

This chapter describes only configuration for IPv6 BGP. For BGP-related information, see Network

Management Configuration Guide.

BGP-4 can only carry IPv4 routing information.

To support multiple network layer protocols, IETF extended BGP-4 by introducing Multiprotocol Border

Gateway Protocol (MP-BGP). MP-BGP for IPv6 is called "IPv6 BGP" for short.

IPv6 BGP puts IPv6 network layer information into the attributes of Network Layer Reachability

Information (NLRI) and NEXT_HOP.

The NLRI attribute of IPv6 BGP involves the following:

• MP_REACH_NLRI—Multiprotocol Reachable NLRI, for advertising reachable route and next hop

information.

• MP_UNREACH_NLRI—Multiprotocol Unreachable NLRI, for withdrawal of unreachable routes.

The NEXT_HOP attribute of IPv6 BGP is identified by an IPv6 unicast address or IPv6 local link address.

IPv6 BGP has the same messaging and routing mechanisms as BGP.
