Xenial users are unable to create vti6 tunnels. [Test case] 1) Create a vti6 tunnel sudo ip tunnel add vti0 mode vti6 local :: remote fdd6:bdb4:5614::2 key 54 2) No error should be displayed and "ip link" should show a new device named "vti0" The ip tunnel call currently fails with the error 'Unknown tunnel mode "vti6"' and no tunnel is created. [Other Info] vti6 mode is supported according to the man page: $ man ip-tunnel | grep vti6 MODE := { ipip | gre | sit | isatap | vti | ip6ip6 | ipip6 | ip6gre | vti6 | any } Modes for IPv6 encapsulation available: ip6ip6, ipip6, ip6gre, vti6, and any. iproute2 4.9.0-1ubuntu2 on *Artful* has no problem creating vti6 tunnels. $ lsb_release -rd Description: Ubuntu 16.04.3 LTS Release: 16.04 $ apt-cache policy iproute2 iproute2: Installed: 4.3.0-1ubuntu3.16.04.3 Candidate: 4.3.0-1ubuntu3.16.04.3 Version table: *** 4.3.0-1ubuntu3.16.04.3 500 500 http://archive.ubuntu.com/ubuntu xenial-proposed/main amd64 Packages 100 /var/lib/dpkg/status 4.3.0-1ubuntu3.16.04.2 500 500 http://archive.ubuntu.com/ubuntu xenial-updates/main amd64 Packages 4.3.0-1ubuntu3 500 500 http://archive.ubuntu.com/ubuntu xenial/main amd64 Packages ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: iproute2 4.3.0-1ubuntu3.16.04.3 ProcVersionSignature: Ubuntu 4.4.0-103.126-generic 4.4.98 Uname: Linux 4.4.0-103-generic x86_64 NonfreeKernelModules: zfs zunicode zcommon znvpair zavl ApportVersion: 2.20.1-0ubuntu2.14 Architecture: amd64 CurrentDesktop: Unity Date: Sat Dec 9 21:55:27 2017 InstallationDate: Installed on 2016-12-06 (368 days ago) InstallationMedia: Ubuntu-Server 16.04.1 LTS "Xenial Xerus" - Beta amd64 (20161206) SourcePackage: iproute2 UpgradeStatus: No upgrade log present (probably fresh install) modified.conffile..etc.iproute2.rt_tables: [modified] mtime.conffile..etc.iproute2.rt_tables: 2016-12-21T17:41:32.869321 ** Affects: iproute2 (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug package-from-proposed xenial -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1737377 Title: Unknown tunnel mode "vti6" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/iproute2/+bug/1737377/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
