1. Physically cable the routers as depicted in the corresponding diagram.
2. The frame relay cloud between R1, R2, and R3 should be partially meshed with no PVC between R1 and R2.
3. The link from R4 to R5 should be 2 Mbps with R4 providing clocking.
4. Each router should have only the necessary physical interfaces turned up along with one loopback each.
5. R3's S0 must use sub interfaces.
