Abstract:
Multiprotocol BGP (MP-BGP) [RFC4760] specifies that the set of usable
next-hop address families is determined by the Address Family
Identifier (AFI) and the Subsequent Address Family Identifier (SAFI).
The current AFI/SAFI definitions for the IPv4 address family only
have provisions for advertising a Next Hop address that belongs to
the IPv4 protocol when advertising IPv4 Network Layer Reachability
Information (NLRI) or VPN-IPv4 NLRI. This document specifies the
extensions necessary to allow advertising IPv4 NLRI or VPN-IPv4 NLRI
with a Next Hop address that belongs to the IPv6 protocol. This
comprises an extension of the AFI/SAFI definitions to allow the
address of the Next Hop for IPv4 NLRI or VPN-IPv4 NLRI to also belong
to the IPv6 protocol, the encoding of the Next Hop to determine which
of the protocols the address actually belongs to, and a new BGP
Capability allowing MP-BGP Peers to dynamically discover whether they
can exchange IPv4 NLRI and VPN-IPv4 NLRI with an IPv6 Next Hop.
