What can I use to accomplish this setup - 2 t1, 2 isp, and a switch with VLANs
Posted on 2009-05-05
I have a T1 at location A, and a T1 at location B. Location A and B are approx 50 miles apart. A and B have different providers. The routers at both location A and B are controlled by their respective Provider.
(Connecting them is a distributed wireless switch. This switch acts like any other switch. Users connect wirelessly, and based on the SSID, they are put on a VLAN. One physical port of the wireless switch terminates as ethernet at location A with untagged VLAN A, tagged VLAN B, another physical port of the wireless switch terminates as ethernet at location B with untagged VLAN B, tagged VLAN A)
So, in essence, it is a REALLY BIG LAYER 2 switch that supports VLAN, tagging, trunking etc.
I want to have this work as such:
People connected to VLAN A will be on the same network as location A, and they will use the router for Provider A to get out to the internet.
People connected to VLAN B will be on the same network as location B, and they will use the router for Provider B to get out to the internet.
This part is easy to setup, just like having them physically plugged into a vlanned switch.
BUT, when either T1 goes down, I need to have the traffic go out the other T1.
What would I need at Location A and Location B?
