So we need to add another type to the subTLV: Mapping (for the scenario of CPE using IPv6, being translated to IPv4 to connect to its peer that uses IPv4, correct?

(was registering tunnel types In SD-WAN ctxt, to let a site which has IPv4 on the WAN talk to another site which has IPv6 on the WAN, we will need to send the packets to a device who can map the v4 address to a v6 address (no NAT, but mapped I call it). The mapping table has nothing to do with NAT and is setup by a controller in most solutions. Now this is working irrespective if the v4 site is NATed (one way or another) or not.

There is no such thing as an IPv6 private address. I'm not sure how to respond to the question. -------------------------------------------------------------------------------- Victorious warriors win first and then go to war, Defeated warriors go to war first and then seek to win.
