Public bug reported:
I have a system connection like this:
---------- /etc/NetworkManager/system-connections/eth2 -----------
[connection]
id=eth2
uuid=c73fb4d2-8383-4d03-a87c-04c8251961bd
type=ethernet
gateway-ping-timeout=12
interface-name=eth2
permissions=
timestamp=1563551266
[ethernet]
mac-address-blacklist=
[ipv4]
dns-search=
method=shared
[ipv6]
addr-gen-mode=stable-privacy
dns-search=
ignore-auto-routes=true
method=auto
route1=1:2::/60,1:2::3,42
------------------ 8< ---------------------
In particular, the last line (route1=) which sets a manual IPv6 route.
Of course this is rather bogus, I'm just using this to test cockpit's
web UI.
On Ubuntu 19.04, Debian 10, and Debian testing this works just fine:
# nmcli c show eth2
ipv6.routes: { ip = 1:2::/60, nh = 1:2::3, mt = 42 }
IP6.ROUTE[1]: dst = fe80::/64, nh = ::, mt = 101
IP6.ROUTE[2]: dst = ff00::/8, nh = ::, mt = 256,
table=255
IP6.ROUTE[3]: dst = 1:2::3/128, nh = ::, mt = 42
IP6.ROUTE[4]: dst = 1:2::/60, nh = 1:2::3, mt = 42
[...]
# ip -6 route show dev eth2
1:2::3 proto static metric 42 pref medium
1:2::/60 via 1:2::3 proto static metric 42 pref medium
fe80::/64 proto kernel metric 101 pref medium
(There, the file is called eth2.nmconnection, but same difference)
On Ubuntu 18.04 however, the route manual is ignored, and only the
automatic link-local one exists:
# nmcli c show eth2
ipv6.routes: { ip = 1:2::/60, nh = 1:2::3, mt = 42 }
IP6.ROUTE[1]: dst = ff00::/8, nh = ::, mt = 256,
table=255
IP6.ROUTE[2]: dst = fe80::/64, nh = ::, mt = 256
IP6.ROUTE[3]: dst = fe80::/64, nh = ::, mt = 101
# ip -6 route show dev eth2
fe80::/64 proto kernel metric 101 pref medium
fe80::/64 proto kernel metric 256 pref medium
Restarting NetworkManager does not help, nor does rebooting.
