Suggested approach with the DOiT labs under the simulated environment:

Look at the DOiT scenario diagrams and VLAN tables.

Make a list of all data links involved in the scenario.
Draw the new diagrams and modify the interface numbering (serial interfaces and fast Ethernet interfaces).
Create a network file for the scenario with the list of routers and Ethernet virtual switch. Configure access or trunk ports on the dynamips virtual Ethernet switch.
Replace ISL configuration with DOT1Q
Network files will be similar to the DOiT Sample scenario explained later in this document, as well as DOiT Scenario 1 network file attached in appendix B.

Modify the initial configuration scripts to reflect the changed interface numbers

Perform required configuration of the scenario on your routers.

Perform routing (IGP and BGP) configuration on the CAT1 and CAT2, as well as IOS features common to a cisco router and a cisco 3550 switch.

Compare results with the SHOWiT engine

Troubleshoot and verify with the TCL procedures supplied with the scenarios in your portal.
