Situation: Have a /8 network that needs to get subnetted. IPs are now configured to fall into /24 subnets, but gateway is still /8 and tower routers are still in switch mode. Hosts are miles apart, so can’t just walk over and reconfigure if router contact is lost.
Question: Is it possible to route this situation?
Gateway 10.0.0.254/8 <->Subnet 10.0.1.0/24
<->Subnet 10.0.2.0/24
Sure. The most specific route (the longest prefix) wins. It would probably be best to use a dynamic routing protocol, though. Like OSPF.
That was quick. Thanks. I will keep working on this. Somehow OSPF seems to have a problem when I give my mockup gateway a /8. At least now I know I am not trying the impossible.
Dont forget also, that you can enter safe mode in winbox by opening a terminal and
pushing CTRL-X and enter safe mode. if you break your connection to winbox, the router will
automatically revert back the setting that cost you network connectivity.
to exit safe mode after your configuration changes are complete, in terminal, press CTRL-X again.
