Hey Clarke, Sorry, I'm just getting around to reading this now. I would say you are correct in your understanding of the way that VRs are supposed to work - routes/TLVs/etc. in one VR should not be leaking into the other. I'm curious, how are you mapping the traffic into their respective VRs? Are these separate and distinct physical interfaces which are bound to their respect VRs or are you using some form of VLAN tagging and mapping unique VLANs into a given VR? Is there any chance you have any type of rib-groups or some other type of vrf-import/export policy in place that might be causing some unintended behavior? Care to share some of your configuration?
