When using Traffic Engineering (TE) in a dual-stack IPv4/IPv6
network, the Multiprotocol Label Switching (MPLS) TE Label Switched
Path (LSP) infrastructure may be duplicated, even if the destination
IPv4 and IPv6 addresses belong to the same remote router. In order
to achieve an integrated MPLS TE LSP infrastructure, OSPF routes must
be computed over MPLS TE tunnels created using information propagated
in another OSPF instance. This issue is solved by advertising
cross-address family (X-AF) OSPF TE information.
This document describes an update to RFC 5786 that allows for the
easy identification of a router's local X-AF IP addresses.
This document is a product of the Link State Routing Working Group of the IETF.
This is now a Proposed Standard.
