1 correctness of response 2 points for Option 2he main office of a NetworkingCompany customer currently connects to three branch offices via three separate point-to-point T1 circuits. The customer network uses RIPv2 as the routing protocol within both the LAN and the WAN. The account manager proposes a change to a Frame Relay network because the costs are lower. A single local loop connection can be installed at the main office with three separate PVCs to connect the branch offices. How can the main office edge router be configured to enable the customer to continue to use RIP as the WAN routing protocol?

Enable Inverse ARP on the serial interface in order to learn the routes to the IP addresses of the remote routers. To prevent the Frame Relay network from causing a routing loop, disable split horizon on the serial interface.Create three separate point-to-point subinterfaces on the serial interface and assign a different subnet IP address to each one. Configure the serial interface with a single interface DLCI number and create frame-relay map statements for each remote site address.
