I have 2 locations connected to each other by a pair of Point to Point T1s and I would like to know how to have a VLAN span between locations without having to use different subnets on each side. (If this is even possible?!?)
I have a HP ProCurve 5412zl switch and 7102zl router at each location. The switches & routers use the default vlan to talk to each other and we have assigned 10.100.0.0/24 to this vlan. We also have VLAN 200 which has been assigned 10.200.0.0/24. I can telnet to a switch on the other side of the network so I am assuming that at least the default vlan is passing across the PtoP.
I would like to have VLAN 200 on both sides of my network use 10.200.0.0/24 addresses but I can't figure out how to configure the switches to do this properly. I don't want to use 10.200.0.0/24 on one side and use 10.200.1.0/24 on the other.
P.S. I know it's not recommended to do this over a WAN connection but we are planning on improving our connectivity to include a fiber-optic connection and we want to plan for the future. If we find our PtoP is flooded with huge amounts of unnecessary traffic we will rethink our strategy.
