routing between layer 3 switches

[rob misz]

Hello,

Our Main Headquarters core switch is a 5400 series. We recently installed a 5400 series switch at a co-location. These two locations have a 1GB fiber connection between them. I would like to setup static routes between locations for so we can connect to  networks that exit on each of these switches.

Can I create and separate VLAN just for the cross connect and create static routes like I listed below?

Switch_A vlan 10

Switch_A(vlan-10)# untag a24

Switch_A(vlan-10)# ip address 10.10.10.254/24

Switch_A(vlan-10)# exit

Switch_A(config)# ip routing

Switch_A(config)# ip route 192.168.20.0 255.255.255.0 10.10.10.1

Switch_A(config)# ip route 192.168.2.0 255.255.255.0 10.10.10.1

Switch_B vlan 10

Switch_B(vlan-10)# untag a24

Switch_B(vlan-10)# ip address 10.10.10.1/24

Switch_B(vlan-10)# exit

Switch_B(config)# ip routing

Switch_A(config)# ip route 192.168.45.0 255.255.255.0 10.10.10.254

Can the uplinks ports(a24) in each switch be tagged for VLAN 10 or do they have to be untagged?
