I have the conection that is annex here.
The router "C" is connected to router "B" via eigrp.
Router "A" is connected to firewall via rip.
Router "A" is a hub frame relay and connect with all routers via eigrp.
I Need connect Router C with Router A via Eigrp.
Do I can make all configuration and leave the same subnet 126.96.36.199/2 in the interface of the router "A" up and then go where is Router "C and connect the cable v.35 to another service provider?.
Leave the serial interface up, with the same IP 188.8.131.52/2, until it reaches the place where this router C, i can generate any problem of communication?
