RFC 8950
Title: Advertising IPv4 Network Layer Reachability
Information (NLRI) with an IPv6 Next Hop

DOI: 10.17487/RFC8950
Multiprotocol BGP (MP-BGP) 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 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 the
advertising of 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 BGP Capability allowing MP-BGP
peers to dynamically discover whether they can exchange IPv4 NLRI and
VPN-IPv4 NLRI with an IPv6 next hop. This document obsoletes RFC
5549.
This document is a product of the BGP Enabled Services Working Group of the IETF.
This is now a Proposed Standard.
STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements. Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
standardization state and status of this protocol. Distribution of this
memo is unlimited.
