You preserver the v4 header. If header > compression removes it, it it put back in place on the receiving side I don't know this is tunnleing, then how this tunneling is setup between two hosts directly? Are you assuming what kind of destination address the source host can get (IPv4 A record or IPv6 AAAA record)?

Same questions above, are you assuming the destination have to support it as well? thanks -Hui > > - Alain. > > _______________________________________________ Softwires mailing list [email protected] https://www.ietf.org/mailman/listinfo/softwires
