You can't but you can use PBR (Policy Based Routing) to send vlan 2 traffic to a different next-hop.

How to implement that in a 3550 switch can you help.

Firstly your 3550 needs to be running the EMI image. If it is running the SMI image it will not support PBR.

Assuming vlan 2 is 192.168.5.0 255.255.255.0

access-list 101 permit ip 192.168.5.0 255.255.255.0 any

route-map PBR permit 10

match ip address 101

set ip next-hop

int vlan 2

ip policy route-map PBR

The above config will send ALL traffic from vlan 2 to the next-hop IP address in the above config.

If you only want to send some traffic then you need to be more specific in your acl.

Thats the version which I have.Can you let me know if PBR works in it

[Jon Marshall]

Yes this should support PBR.

Jon is correct in his answer. Here is a link which will run down the flexability you have with PBR.
