Thanks for your input. What it boils down to is this, can BPDUs traverse a T1? If so then then a spanning tree forms from one end to another and it does what I need, if not will have to find another way. This all has to be handled at level 2, the traffic flow consists of frames and multicasts, no packets. no network addressing. It's a propritary industrial application protocol developed back in the mid 1980's that was designed to work only at the frame level. Kinda sucks I know but it pays very well. Cant complain in this economy...

Give this a thought: 1) Create a loopback interface on each router and assign IP addresses to the loopbacks. 2) Give the serial interfaces on the routers IP addresses as well. 3) Build a tunnel using the loopbacks as endpoints 4) Put the tunnel and the ethernet interfaces in the same bridge-group 5) Use floating statics to move the traffic across your preferred link unless the link goes down. This is a pretty generic solution. There may be something better depending on your situation...more details?
