Hi all,

im trying to configure vlan on my switch, port f0/1 is set as trunk, connected to cisco router. on my switch, port f0/2 & f0/3 belong to vlan2, and f0/4 & f0/5 on vlan3, all the others are vlan1 (default). servers on port 2 & 3 see each other, and so with port 4 & 5, however, going out to the router doesnt work. i tried pinging an outside ip but it says destination unreachable. port f0/1 (trunk) has been allowed (which i know allows all by default). the cisco router port (where the switch is connected) is configured with secondary ip addresses. primary ip for vlan2 and secondary ip for vlan3.

am i missing something? are there additional configuration on my router to be done?

TIA,
etcbin

You need to set the router to accept a dot1q
trunk (assuming you use dot1q and not ISL) on
its port.
This is a feature at the MAC layer, not IP
layer.
Then You can create VLANx interfaces for you
VLAN1 and VLAN2, with eacht their own address.

HIH,
kind regards,
