Lab 8: Frame Relay

Task

Topology

1. Configure Frame-Relay DLCI on frame-relay switch as per given in topology.
2. Configure IP Addresses as per given in topology. Make sure R1 to R2 used point to point link in frame-relay encapsulations.
3. Make Sure R3 and R4 not assigned DLCI Dynamically. 
4. Configure EIGRP over this scenario.
5. Make sure R3 loopback and R4 loopback addresses are ping each other. (You are not allowed to disable EIGRP split horizon)

Solution

Task 2: Configure IP Addresses as per given in topology. Make sure R1 to R2 used point to point link in frame-relay encapsulations.
