      Hello!

      Quagga  not changing kernel routes. I see immediate changes on link status change and correct routes in Quagga OSPF, but no changes in system routes (Diagnostics - Routes).

      Routers links are OpenVPN Site-to-site.
      Connected networks (LAN) Router ID 1.1.1.1N Network 192.168.N.0/24

      For example look at 1.1.1.13 and 1.1.1.12. From the diagram we should say that they interact via 172.18.3.200/30 with cost 15. Quagga agree with us. But in real they interact through router 1.1.1.10 because kernel routes not in actual state.

      kernel route 192.168.2.0/24 via 172.18.3.1 - cost 20
      Quagga route 192.168.2.0/24 via 172.18.3.101 - cost 15, direct link

      Here are config of 1.1.1.13 and logs

          Should you add this to the topic you linked? Or just remove topic.
