When you do "vzctl set CTID --ipadd 2001:1234:1234:1234/64 --save", OpenVZ creates a route only for the network address (2001:1234:1234:1234::), but not for the entire /64 subnet which is unexpected behaviour already. Inside the container, OpenVZ automatically adds the network address (2001:1234:1234:1234::) to venet0. 2001:1234:1234:1234:: is now reachable from the outside If you add 2001:1234:1234:1234::1 as an address inside the container, it should send a NDP packet to update neighbours about the new IPv6 address (including the router) but what we see instead is 2001:1234:1234:1234::1 staying unreachable. OpenVZ in this case treats the 2001:1234:1234:1234::/64 subnet as a single address (which is 2001:1234:1234:1234::) instead of the subnet we requested and throws away all subnet information. How we expect it to work instead: "vzctl set CTID --ipadd 2001:1234:1234:1234::/64 --save" should add an entire /64 route and allow the container to use the entire /64 subnet as outgoing IPv6 address vzctl should not by default add an IPv6 address from this subnet OR add 2001:1234:1234:1234:: by default to the container. Inside the container we should now be able to add 2001:1234:1234:1234::1 as another IPv6 address to venet0 and OpenVZ kernel/the hardware node should forward NDP packets for updating neighbours including routers with the new IPv6 address. The addresses 2001:1234:1234:1234:: and 2001:1234:1234:1234::1 should now be reachable from outside. I hope that I explained this enough in detail so everyone reading should get an idea of what we mean. - -- Best regards Kevin Holly - r...@hallowe.lt - http://hallowe.lt/ -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBAgAGBQJVgz/dAAoJELAaqP3QtzpMLlwH/2nYUll/ZwkkmQbYCZLRWAMZ h90rdK8zh5MRKTSSlMMO6AEBc3yKiw2F5nSHpAIKS5GuvtRbKs7qkHDM3BruSvg6 W60D0tiYdIQLKFCEgldo5aPmGdJirGA/DV8nq1bEYlQX41nC9rsuvRUPbupIr24n Y6YN2J34BIaTmkXrAj2kjL+O0h6AUlgTOyitohd8jzmc4aki7jn3rsuoDDC6yN38 mKBp1j992zJnWPHSekmyCYAJzGRlD0JAAamasFTxlkV/5Gd3vZoFIX6tkrj7Wfu2 /CGgGM9+3ubPdW9CJeBPSGO92VxAyomLf7Y68ezVO0zuK/FuqqMPwaADJ64eCLU= =sbdL -----END PGP SIGNATURE----- _______________________________________________ Users mailing list Users@openvz.org https://lists.openvz.org/mailman/listinfo/users
