I'm not sure what you mean because of wrapping.
You mean this?
A(IP: 192.168.0.2)
(NM: 255.255.255.0)
(GW: 192.168.0.1)
B(IP: 192.168.0.1) (IP: 192.168.1.2)
(NM: 255.255.255.0) (NM: 255.255.255.0)
C(IP: 192.168.1.1)
(NM: 255.255.255.0)
(GW: 192.168.1.1)
You should change the GW of C into 192.168.1.2.
C does not know the route to 192.168.0.2; B does.
