Yes, you need to set up the ethernet for 2 sub-interfaces and set the encapsulation to isl and the isl id # to the vlan # you set up on the switch. if the router config is correct the router will route the vlans across the sub-interfaces on the router.

One last question though. For external router, routing between vlans if I have just one FastEthernet interface on the router can I route between vlans?

If you have any 100 MB ports on your switch, you can run trunking. set trunk (mod/port) on isl If this trunk is running into a router, you need to create the subinterfaces on the router to enable routing between VLANS. int fa1/0.100 ip address (the subnet of the vlan) encap isl (the vlan #) HTH, Scott ""George Siaw"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Do I need an Sc0 port when routing between Vlans?
