Question 4

HW has a Frame Relay network with two sites (a headquarters site and a remote site) connected by a single PVC. RIP version 2 is running in the network. A new remote site is added and HW has ordered a second PVC between this site and the headquarters site. All Frame Relay interface IP addresses are in a single subnet. The customer configured Frame Relay DLCI mappings and can successfully ping from the new remote to the headquarters site as well as to the other remote site.
