My Cisco 2520 Router arrived on Friday from CiscoKits.  I’ve been fairly sick the past few days, so I didn’t get to do my labs like I wanted to this weekend, however I did manage to have enough energy one day to setup the 2520 as a Frame Relay switch.  It didn’t take very long, and now everything is setup and in place so I can do my Frame Relay labs.    My lab continues to grow, I’m now up to 5 routers, two PIX firewalls and two switches.

Once I finished connecting all the DCE/DTE cables to the correct serial interfaces and finished my configs on both sides I ran a sh frame route to verify that the status of all the serial interfaces was active.

The configuration for the Frame Relay Switch was from TheBryantAdvantage.  He has a lot of useful material, and is a great instructor.  Be sure and check out his web site for more labs and information as well as his courses he provides for both CCNA and CCNP.
