Hello.
I have a bunch of birder routers, and the troublesome router is connected to
some of them via LAN and to some of them via WAN tunnels.
For some reason it always chooses a WAN route, regardless of it's metric:

gif1 and vlan57 are in different areas, that is something that is likely
relevant. What you get from 'show ospf state'?

Where (which area) is
192.168.57.254?
It's in area 0, the "gw" router and 192.168.57.254 are connected via
vlan interface over a 100 Mbit/s link.
How internal routes for 192.168.57.254 looks if you
enable/disable gif1?
Pretty much identical, because "gw" is locally connected to 192.168.57.0/24:
