I need a clarification on the following:
- We have about 25 sites that are linked to a core router. The 25 sites have different types of WAN links, some are on Frame Relay, P-To-P, or ATM. After reveiwing the network diagram,I inherited from a former Ntwk Engr, and and the routers' config files, I became unclear on why the remote sites routers having Frame-Relay and P-to-P linked to the Frame-Relay cloud; however, on the core router configuration file, each one of the remote sites has an ATM interface configured for it. Can someone explain to me how a Frame-Relay or P-to-P link on one end is linked to an ATM on the other end?
Thanks in advance,
