I plan to run multiple VRFs on the layer 3 switch (3750) at our spokes.
However, I don't want to expand my MPLS cloud from the hub all the way to the spoke routers (2811) because spoke-hub WAN links are satallite links and these links are not very stable. I don't want to bring this instablity to my MPLS core.
So the question is, how do I transport multiple VRFs to the MPLS cloud at the core without expand the MPLS cloud all the way down to the spoke?
if the question is "how could I do traffic separation when I couldn't expand my MPLS L3VPN", the answer is:
1. L2 solution = VLAN
2. L3 solution = multi-VRF, or VRF light
With satellite links we normally leave the traffic from spokes in the global route, then on Aggregation point we insert the traffic in to the MPLS cloud with a "VRF selection" based on source IP or PBR.
