I have a monitoring system that needs check devices that sit in overlapping private ip space, and I was wondering if there is anyway I could use some kind or VRF type solution that would allow me to label the "site" the traffic is intended for.  The upstream router supports VRF/MPLS, but I need to know how I can get the server to label the traffic.  I would appreciate any input.

In linux, you can manage the different routing tables.

You can do this with the iptables + iproute2 series of commands.  The tables 254/255 are the main and local tables.

You shouldn't have too much trouble finding information via google on how to manage your needs.
