CSS 11506 Routing Question

Dear All,

I have just inheirted a pair of two legged (bridged) CSS11506 (software version 07.50.1.03). My goal is to enable ip communication between two vlans ( Vlan X [172.25.2.0/24] , and Vlan Y[192.168.34.0/24] where CSS sits).

The question is would it be ok if I add an static route entry on CSS to redirect traffics to Vlan X via Cisco3550 (without passing thru CSS)? Servers in Vlan X need not be handeled by CSS in Vlan Y.

It is because if doing so the traffics initiated from Vlan X would not pass thru CSS, but the return traffics from Vlan Y would..would this cause problem with CSS?

Cisco3550:

Vlan X :192.168.34.252 / 24

Vlan Y :172.25.2.252 / 24

CSS11506:

Vlan X : 192.168.34.253 /24

FW : 192.168.34.254 /24

ip route 172.25.2.0/24 192.168.34.252

ip route 0.0.0.0 0.0.0.0 192.168.34.254

Traffic Path:

Vlan X > Cisco3550(intervlan routing) > Vlan Y

Return traffic :

Vlan Y > CSS11506 > Cisco3550(intervlan routing) > Vlan X

I hope I made myself clear, I have more detailed diagram available if needed.

Thanks for any help in advance,

Tony
