There was a virtual link. The virtual link was from R1 over to another router across the Frame Relay cloud. R1 is an ABR connecting Area 0 and Area 1. Area 0 is the Ethernet LAN. Area 1 is the Frame Relay cloud. For some unknown reason, there's an Area 2 also on the other side of Area 1. Does that ring a bell regarding any gotchas??
