Bug Description
[Impact]
netplan.io users who define custom routes
[Test case]
1) Configure netplan.
2) Add a route:
[...]
routes:
- to: 10.10.10.0/24
scope: link
3) Validate that the route is correctly added to the routing table (using 'sudo ip route').
[Regression Potential]
Adding a feature to allow setting scope for routes or other route parameters lead to additional complexity in the configuration for the routes. As such the additional setting may confuse systemd-networkd if set incorrectly in attempting to add routes that would be invalid or useless. Any issues with adding routes (as evidenced in logs from systemd-networkd) should be investigated as possible regressions caused by the addition of the 'scope' parameter.
---
I have an hosted server and for some reason, I only have a single global ipv6 with prefix /128.
To be able to reach the world using IPv6, I have to declare a route to the router, and then the default route:
In traditionnal ifupdown, this is done using the following lines:
post-up /sbin/ip -family inet6 route add 2001:41d0:
post-up /sbin/ip -family inet6 route add default via 2001:41d0:
I think that in networkd it should be declare as:
[Route]
Destination=
Scope=link
[Route]
Gateway=192.168.0.1
Actually, I don't find anyway to express such route in netplan. I can easily define the gateway route setting 0.0.0.0 as 'to', but it look like there is currently now way to define the "link" scoped route.
netplan "route" should support a scope attribute that match networkd Scope attribute.
