Here's how we did it in class.

Add another router named ISP (or whatever) and connect it to the router in your local network you want the traffic to pass through.

Put the passive interface command on the interface connected to the ISP router in order to suppress your routing updates.

Put a static route 0.0.0.0 0.0.0.0 to the ISP router and redistribute that route to the other routers in your LAN.

From here, all of your routers will forward the data out to the "internet." In order for that data to return you'll need to have NAT set up. If you want your local hosts to ping "websites" you can either use loopbacks on the ISP router or servers attached to it. You'll also need to set up a local DNS server to convert the url's to the ip address of the loopbacks/servers. The cool thing about using servers instead of the loopback is that you can actually go into the browser of your local hosts and browse to those websites. This comes in handy if you want to set up ACL's where you can test connectivity by pinging but still block web traffic.

This may not simulate the actual routing outside of your network but it does simulate what you need to do to get your local network communicating with the WAN. Add in your own DHCP server and you've got a fairly decent lab setup that covers most of the communicating with WAN topics.
