Well, before I asked this question, I searched a lot and couldn't find a proper answer (or the question was wrongly asked).
I want to connect a bridge to a GRE tunnel on netplan. I can successfully do the connection, but the routing table doesn't get updated correctly. I am forced to add the route manually for it to work.
So, here's my netplan setup:
network:
version: 2
ethernets:
enp1s0f0:
dhcp4: no
accept-ra: false
addresses:
- 192.168.0.100/24
routes:
- to: default
via: 192.168.0.254
match:
macaddress: d8:5e:d3:43:cd:ae
set-name: enp1s0f0
nameservers:
addresses:
- 1.1.1.1
- 1.0.0.1
- 2606:4700:4700::1111
- 2606:4700:4700::1001
tunnels:
gre1:
mode: gre
remote: 192.168.100.150
local: 192.168.0.100
bridges:
br1:
dhcp4: false
dhcp6: false
optional: true
interfaces: [ gre1 ]
addresses:
- 172.16.20.2/30
routes:
- to: default
via: 172.16.20.1
scope: link
table: 100
routing-policy:
- from: 172.16.20.0/30
table: 100
With the above configuration, the gre1 has a state UNKNOWN and the br1 state is DOWN. If I try to ping 172.16.20.1 it fails.
But, if I run:
ip route add 172.16.20.0/30 dev gre1
I can ping without any issues.
Anyone has a clue on how to solve this riddle?
