Hi, I've implemented v4traversal-00 draft. I agree Francis, the IPv4 mapped address has a special meaning by RFC 2553 API. It is not preferable to use the mapped address in IPv6 headers (See the following the drafts) draft-itojun-v6ops-v4mapped-harmful draft-cmetz-v6ops-v4mapped-api-harmful In our code based on KAME, the IPv6 implementation discard a IPv6 header which has the v4 mapped address for sanity at ip6_input() and ip6_rthadr2(). We also need to add the mapped address in an address list (the list of all addresses which the node has) to receive the header. This is somehow uncomfortable because the mapped address is actually not routable. Can the DT summarize your discussions how you reach to use IPv4 mapped address? regards, Koshiro At Mon, 20 Mar 2006 20:42:09 +0100, Francis Dupont wrote: > > In case there will be not enough time for global questions: > - the I-D is draft-ietf-mip6-nemo-v4traversal-01.txt, isn't it? > - there are some IPv4-mapped IPv6 addresses in (encapsulated) IPv6 > headers, this is against IPv6 rules and can become an issue > with all the sanity "mapped address -> drop packet" checks > in IPv6 current codes... > - the IPsec stuff is severely underspecified, I have no idea reading > the I-D how the RFC 3776 IPsec SAs are established. > - (AGAIN) what is the position of the I-D versus the well known > "road warrior" IPsec VPN with NAT traversal (where the keepalive issue > is solved BTW) ? > > Regards > > Francis.Dupont@point6.net > > _______________________________________________ > Mip6 mailing list > Mip6@ietf.org > https://www1.ietf.org/mailman/listinfo/mip6 _______________________________________________ Mip6 mailing list Mip6@ietf.org https://www1.ietf.org/mailman/listinfo/mip6
