[nsp] Best choice?

[Voll, Scott]

I need to know what everyone thinks is the best product for the
scenario:

All the ISPs are located 60 miles north of us and our partnering agency.
We have layer two transport(100mb) via two different carriers to the
ISP.  We and the other agency will also interconnect via layer 2 for
reduncancy.  Looks something like this:

ISP ---- device in question -------layer 2 transport 1
----------------------- Cisco 7200 (us)
             |
|
             |
Layer 2 Transport 2
             |
|
             |---------------------Layer 2 Transport 2
----------------------- ???????? (partner agency)

We are thinking we will need to run BGP in order to get redundancy,
right?  The device in question would best be layer 3? Switch? Cisco?
Other? Or do I just put a layer 2 switch up there?  Any comments are
highly valued.  It is possible that we may also want to add ISPs in the
future.  Which could make this a single point of failure :-( but what
would everyone highly recommend.  Again it doesn't have to be cisco, but
being it is a cisco list you might want to include a cisco model also
;-)

TIA
