I don’t understand well OSPF, but following the manual got it working on mesh of 5+ routers.
one of them is attached to subnet (192.168.100.0/24) managed by 3rd party router. I want to advertise the route to that network.
the MT router is assigned IP 192.168.100.1, the router on the other side has 192.168.100.2. The connecting interface is not bridged, on purpose.
the MT router properly advertises it’s own IP, routing works correctly, etc. When on remote box I set-up static route to 192.168.100.x via 192.168.100.1 everything’s OK.
