Public bug reported: cloud-init trunk and xenial, yakkety, zesty and artful all fail
A network config with a ipv6 gateway route like: subnets: - type: static address: 2001:4800:78ff:1b:be76:4eff:fe06:96b3 netmask: 'ffff:ffff:ffff:ffff::' routes: - gateway: 2001:4800:78ff:1b::1 netmask: '::' network: '::' For eni rendering, this should create a post-up/post-down route command that generates a default ipv6 route entry, like this: post-up route add -A inet6 default gw 2001:4800:78ff:1b::1 || true pre-down route del -A inet6 default gw 2001:4800:78ff:1b::1 || true However, what is currently generated is this: post-up route add -net :: netmask :: gw 2001:4800:78ff:1b::1 || true pre-down route del -net :: netmask :: gw 2001:4800:78ff:1b::1 || true That does not install the route correctly as a default gateway route. This is fallout from commit d00da2d5b0d45db5670622a66d833d2abb907388 net: normalize data in network_state object This commit removed ipv6 route 'netmask' values, and converted them to prefix length values, but failed to update the eni renderer's check for ipv6 default gateway. ** Affects: cloud-init Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
