Router on a stick config cant ping

[tolinrome tolinrome]

I'm trying to build a router on a stick and cant figure out why nothing is pingable. I cant even ping from the switch to the client.

Clients have their respective ip's 10.1.10.2 and 10.1.20.2 and correct default gateways configured and the port from the switch to the router is trunked. On the switch vlans 10 and 20 are created and up. Everything on the router looks ok. Can anyone help on what the problem is? I cant ping from any device ot any other device. Thanks.

Hello

Switch

The switch interface connecting to you router - this needs to be a trunk interface - would that be fa0/3  in your post and is it running dot1q  encapsulation?

Also make sure the switch its running as a host siwtch ( ip default-gateway x.x.x.x ) and doesnt have ip routing enabled.

Router-

int fa0/1.2

encapsulation dot1q 20

ip address 10.1.20.1 255.255.255.0

Yes, it was the Router, I didnt know that the number after the encapsulation dot1q 20 - had to be the vlan id number!

Thanks.
