The problem here isn't the switch. It's the fact that you have three
routers, none of which have interfaces on the same IP subnet.

This would not work. These ports are connected to
eachother. You would use the "no switchport" command and assign a IP
address when you have a switchport connected to a router. Below is a
config that I think might work for your scenario. Not sure though. Try
it and let us know. Thanks. Best of luck.

3550-2 int vlan 200 ip address 135.5.200.2 255.255.255.0
