I'm trying to come up with the best way to layout TE tunnels between a couple POPs. On one side I have a pair of 7600s with 3BXLs running SRB1; we'll call this A and B. On the other side I have a pair of ME6524s; we'll call these C and D. Each pair of routers serves are the core in their respective POP, with the edge devices dual-homing to each core router. The first router in each POP is connected via GigE over about 80 miles of fiber through numerous towns using media converters. The second router in each POP is connected in a similar fashion over another strand in the same fiber bundle. A 3rd connection is being made with radios and will terminate in the first router in each POP. At some point in the future the second fiber path will be broken in the middle to drop off services in that town. I anticipate either a 7201 or another 7600 depending on bandwidth needs vs costs; we'll call this future router E.
My short term needs mainly involve FRR. However as our backbone bandwidth needs grow we'll likely need the full set of TE features in the not-too-distant long-term. Unfortunately we do not have 2 diverse fiber paths to work with at this point in time. My initial thought was that I should build tunnels for A-C, B-D, A-B-D-C, and B-A-C-D. However the radios complicate that design in my eyes. How do I indicate that the radio path is more costly than the fiber path for as far as MPLS TE is concerned? Do I need an explicit path defined for each possible combination of paths? Am I simply not looking at this in the right light?
