unless you are advertising a host route, I don't think there would be any effect here. and to be truthful, I'm not sure that the routing process cares one way or another so long as the particular router's LAN port is functional.
the routing table would show that host route 172.20.10.1 is reachable via network 172.20.10.0 as long as the router interface in network 172.20.10.0 is operational..... haven't tested, just thinking out loud.
