Is it possible to configure intervlan routing in 3500 for SOME vlans?

I'm going to create 4 vlans in a 3550 switch and I want to configure intervlan routing between only 3 of them. Is it possible? If yes then how to configure? Thanks.

1st thing to remember is this. You can only route between vlans if you have a router, or switch that can route. So if you have that, then yes you can route between 3 of 4 vlans. In your case, you'd just need to create a routed interface for each vlan that you want to talk to each other. The one you don't want to have routed....just don't create the interface. Simple.

Here is an example.

interface vlan 1
ip address 10.1.1.1 255.255.255.0
no shut
interface vlan 2
ip address 10.1.2.1 255.255.255.0
no shut
interface vlan 3
ip address 10.1.3.1 255.255.255.0
no shut

and just don't create interface vlan 4.

The 3550 should do a nice job for what you want to do . Follow the previous posters insructions , you will also have to specify at the port level what vlan and whether you want it to be a trunk or regular port . Do you have switches below the 3550 or are all your connections on the 3550 ?

Thanks everyone
Actually I already know how to enable routing in 3550 but just don't know how to disable routing for certain VLANs.

Thanks again.

On the VLANs that you don't want routed, do this....

interface vlan9
no ip address
