Public bug reported: On an IPv6 network, routes have a marked lifetime.
So, if you are connected to two IPv6 networks you may have multiple default routes. Not such a problem. kalki:[~]% ip -6 route 2001:44b8:75ee:19d2::/64 dev eth1 proto kernel metric 256 expires 22sec mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev virbr0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev eth0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev eth1 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 default via fe80::200:ff:fe00:0 dev eth1 proto kernel metric 1024 expires 22sec mtu 1500 advmss 1440 hoplimit 64 default via fe80::203:47ff:fe8b:66f4 dev eth0 proto kernel metric 1024 expires 24sec mtu 1500 advmss 1440 hoplimit 64 [ what is odd is that eth0 has no link route on it, but whatever this bug is not about that ] Note the expiration times on each route, and let's do this again: kalki:[~]% ip -6 route 2001:44b8:75ee:19d2::/64 dev eth1 proto kernel metric 256 expires 17sec mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev virbr0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev eth0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev eth1 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 default via fe80::200:ff:fe00:0 dev eth1 proto kernel metric 1024 expires 17sec mtu 1500 advmss 1440 hoplimit 64 default via fe80::203:47ff:fe8b:66f4 dev eth0 proto kernel metric 1024 expires 1sec mtu 1500 advmss 1440 hoplimit 64 kalki:[~]% ip -6 route 2001:44b8:75ee:19d2::/64 dev eth1 proto kernel metric 256 expires 16sec mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev virbr0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev eth0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev eth1 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 default via fe80::200:ff:fe00:0 dev eth1 proto kernel metric 1024 expires 16sec mtu 1500 advmss 1440 hoplimit 64 default via fe80::203:47ff:fe8b:66f4 dev eth0 proto kernel metric 1024 expires 0sec mtu 1500 advmss 1440 hoplimit 64 kalki:[~]% ip -6 route 2001:44b8:75ee:19d2::/64 dev eth1 proto kernel metric 256 expires 16sec mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev virbr0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev eth0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev eth1 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 default via fe80::200:ff:fe00:0 dev eth1 proto kernel metric 1024 expires 16sec mtu 1500 advmss 1440 hoplimit 64 default via fe80::203:47ff:fe8b:66f4 dev eth0 proto kernel metric 1024 expires 0sec mtu 1500 advmss 1440 hoplimit 64 kalki:[~]% ip -6 route 2001:44b8:75ee:19d2::/64 dev eth1 proto kernel metric 256 expires 15sec mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev virbr0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev eth0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev eth1 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 default via fe80::200:ff:fe00:0 dev eth1 proto kernel metric 1024 expires 15sec mtu 1500 advmss 1440 hoplimit 64 default via fe80::203:47ff:fe8b:66f4 dev eth0 proto kernel metric 1024 expires 21474836sec mtu 1500 advmss 1440 hoplimit 64 kalki:[~]% ip -6 route 2001:44b8:75ee:19d2::/64 dev eth1 proto kernel metric 256 expires 14sec mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev virbr0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev eth0 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 fe80::/64 dev eth1 proto kernel metric 256 mtu 1500 advmss 1440 hoplimit 4294967295 default via fe80::200:ff:fe00:0 dev eth1 proto kernel metric 1024 expires 14sec mtu 1500 advmss 1440 hoplimit 64 default via fe80::203:47ff:fe8b:66f4 dev eth0 proto kernel metric 1024 expires 21474836sec mtu 1500 advmss 1440 hoplimit 64 That route (on dev eth0) has 'expired' but the time seems to have gone to infinity. It stays there for a while - after a few minutes (the time it took the collect this information, submit to lauchpad and me login) the route disappears. But it seems to be taking a longer time that you would expect. Well, certainly I would expect.
