Let me say up front, I don't have much experience in MPLS, I have only played with it in the lab and not all that extensively either. But CN is simply trying to get an idea of what to expect to go that road. Is "nrf" saying not to advance in this field by studying Cisco's way of emphasising MPLS ? You know, we all have our doubts, he's brave enough to come to this group and ask questions. As far as L3VPN's, why not concentrate on that at least to start with. It's still one reason to do the MPLS thing. By just doing that he'll need to touch on many aspects of MPLS anyway. He will still use either LDP or RSVP, he still will use the LSP establishment, he might as well learn the TE options available for establishment of those LSP's. He'll need to learn how to use the LSP's for pushing traffic over them. He'll learn what and how the labels get pushed/popped. Then why not study it that way. He's not advancing his MPLS skills, he might not have any yet. He's simply trying to see if he will be able to utilize any of the skills he will have to learn to make it worth it his while.
Well, maybe someone else with more experience in MPLS arena and someone more objective can give a better insight as to whether there is a demand for these skills.
