I know it is possible but I am having difficulty getting this to work. I am not a cisco guru but I can program a switch. Here is the scenario. I know I am only a few steps off.
I have a 2950 switch connected to a 1720 router. The switch is set up to have a 2 vlans. Vlan 1 has ports 1 - 5 in it. Those ports can ping the fast ethernet port of the router. Both the primary and secondary ip's can be pinged from the devices on vlan 1. vlan 2 cannot ping anything. Ports 6-11 are on vlan 2. Port 12 is trunked with both vlans and leads to the router. I can only get 1 DG in the switch, which is the primary fast ethernet ip in the router, which is also vlan 1's DG. Can anyone tell me why vlan 2 is not getting out? Any help would be great! thanks!
