Jared, Thank you for your reply. The one issue I have is how can I label traffic to match a given table (i.e. ping VRF or snmp VRF). I don't see any way this can be done with normal BSD sockets, finding a way to get my application to 'color' the traffic has been a little evasive. The developers I am working with are using Mule for their data collection. I would really prefer to add an MPLS tag to mark the traffic, but I will investigate what I can do using the Linux routing features and 802.1q tags. --- Brian Raaen Network Architect braaen@zcorum.com On Tue, Aug 23, 2011 at 09:50:30AM -0400, Jared Mauch wrote:

While I have found some information on a project called linux-mpls I am having a hard time finding any solid VRF framework for Linux. 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.
