Might need to know a little more about the layout here for a better answer.

Subject: Routing to multiple uplinks

This may be slightly off topic however I have a very unique situation  
where I need to provide two diverse paths to a major stock exchange.  
Each host may either use route A or B for any given reason to access  
this particular exchange using two distinct routers and target address.

The applicatiOn running on these hosts must only see/use one target  
address this needs to be transparent as possible. NIC bonding/teaming  
on the host side isn't a viable solution because of the latency  
overhead same goes for vrrp/hsrp.

I believe my only option here is to setup multiple default routes with  
a preferred path of some sort. This seems to be possible using ip  
route2 on Linux.

This just seems wrong on many levels and I thought I would post here  
because I know there is something obvious I'm missing.
Please clue me in.

Thanks.
