Frame Relay mappings
So why can’t RouterA talk to RouterB across the Frame Relay network? To find that out,
take a close look at the frame-relay map statement. See the problem now? You cannot use
a remote DLCI to communicate to the Frame Relay switch; you must use your DLCI number!
The mapping should have included DLCI 100 instead of DLCI 200.
Now that you know how to ensure that you have the correct Frame Relay encapsulation
and that DLCIs are only locally significant, let’s look into some routing protocol problems
typically associated with Frame Relay. See whether you can find a problem with the two configurations
in Figure 11.11.
