   When using Traffic Engineering (TE) in a dual-stack IPv4/IPv6
   network, the Multiprotocol Label Switching (MPLS) TE Label Switched
   Paths (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 RFC5786 that allows for the easy
   identification of a router's local X-AF IP addresses.
