@RonMaupin Checked in eve-ng 7200VXR and in PacketTracer: PT didn't recognized 0.0.0.0 0.0.0.0 and didn't built neighbor connection; 7200VXR - all good.

The current Cisco IOS is actually smart enough to figure out that network 0.0.0.0 0.0.0.0 area 0 is actually network 0.0.0.0 255.255.255.255 area 0. It can correct most masks to wildcard masks. We discovered this by accident when an engineer put it in backwards and it worked, then Cisco confirmed that it can fix most things.
