my current Cisco lab.
On the left two 1712 routers and on the right from the top: A 2520 router, a 2511 terminal server, two 2950 switches and a 3548 switch. The 2520 is the latest addition to the lab, the plan is to use it as new or second frame relay switch.
Four 3640 routers, the three at the buttom are conncted as triangle.
From the top: A hub, two 2516 routers, a 2501 and a 2521 router. The 2521 is configured as a frame relay switch.
