I'm trying to ping one PC on one particular VLAN (VLAN 80) from another PC on a different VLAN (VLAN 50). I have a layer 2 switch (Cisco 2950T), so I can't do it from within itself.

How would I be able to ping a different PC on a different VLAN through the router? Would it done through the "IP routing" command from the switch or is there another way?

    You cannot do that with a layer-2 switch. Routers route between networks. If you had a layer-3 switch, you could enable routing on it. A layer-3 switch has a routing module, and you would create SVIs and address them. When you enable routing, the layer-3 switch would automatically route packets between the two different networks.

  • You have to use a router to do inter vlan routing. The technique is called 'router on a stick'. Or if u have L3 switch to which these PCs are directly connected then u have to create Interface VLAN corresponding to each VLAN , like Interface Vlanif 80 and Interface Vlanif50. The IP address of these Vlanif would be the default gateway of the PCs. Switch will do routing and ping would be successful.
