Frame Relay Setup 8 Points

Configure IP across your Frame Relay network, as displayed in Figure D-2.

■ You have to use static maps for each protocol. No dynamic mapping is permitted.

■ No subinterfaces are allowed on any router except on R3.

■ You can assign a subnet from your Class B range.

■ Use LMI-type Cisco only and do not rely on auto-sensing the LMI type on any routers. All router interface types are DTE. The Frame Relay port type is DCE.

■ Do not use the keyword broadcast for the Frame Relay link between R3 and R4 when mapping IP. (Hint: use a tunnel interface for routing IP across this cloud.)

■ Make sure that you can also ping the local interface from each router configured for Frame Relay.
