what is the best way to interconnect 3 data centers..., partial mesh or full mesh.
we have CWDM/DWDM between 3 DCs and layer-3 links to ISP which will serve as backup 100mbps links.
Is DC-A to be connected to DC-B and DC-C (Partial mesh) best idea or full mesh DC-A to DC-B and DC-B to DC-C and DC-A to DC-C
which is best for the design. IS-IS will be running at core level. for all dc 6500 switches and 7600 routers will be used.
upgradable for mpls when we have SIP line cards in few months..
what do you guys recommend..
