This lab provides a scenario on troubleshooting Inter-VLAN routing with a
Route Switch Module (RSM) on a Catalyst family switch. When it comes to
troubleshooting the RSM, the first thing to do is to think of it as a simple external
router. It is very seldom that a RSM specific issue is causing a problem
when Inter-VLAN routing is concerned. Therefore, two main areas where this
could occur are RSM hardware related issues or Inter-VLAN configuration specific
issues (mostly related to the interaction between routers and switches)....
