FabricPath & Layer-3 VPNs (VRF) between 2 Data Centres

[peter.stephan]

Hi there,

I'm looking at deploying FabricPath for layer-2 extension between 2 Data Centres.

We also have the requirement for providing layer-3 services between the 2 DC, as in Layer-3 VPN (MPLS VPN).

The alternative technology was MPLS, with full blown Layer-3 VPN, and Layer-2 VPNs through AToM or VPLS.

My question is, how can we provide VRF support over FabricPath?? Can we use 2 routers with VRF lite configuration in each DC, then dot1q on the trunk through the Fabric Path? Or just VRF Lite on the layer-3 terminating routers, with a specific VLAN for interconnecting the different VRFs?

Thanks,

Fabricpath is L2; not related to the L3 technology you want to use; if VRF are in use you can just use VLANs which is described in your first scenario : "use 2 routers with VRF lite configuration in each DC, then dot1q on the trunk through the Fabric Path"
