I'm trying to setup a highly redundant configuration of
two routers and two rstp capable switches behind them.
Each of the router is connected to each of the switches,
and it's two interfaces are part of a bridge group.
this way i can handle router and/or switch failure without
disconnecting the site.
The problem is that this a remote site which must not go offline by
any means, and thus the unusual setup.

Hope that this explains it.
