I'm a CCNP and have decent experience in the industry, however I have not worked for a service provider and do not have direct MPLS experience - only the education required for the CCNP tests. My understanding of MPLS is that it is a service provider technology that allows that provider to securely, quickly and efficiently provide virtual networks for their clients which will allow internal addressing to span the provider network, even if multiple clients use the same internal addressing. The end clients only use their standard routing protocols across the provider network and do not need to know anything about MPLS since it is transparent to them. Lately I’ve been seeing a few whitepapers that talk about using MPLS within large campus environments but I would be a bit surprised to see this used a lot because of the size of the campus that be able to gain the benefits of using it. (am I wrong?)
What I’m seeing lately though is that there are a lot of job advertisements that are looking for MPLS experience and are not talking to you unless you have it. In your opinion are they looking for 1) a former service provider engineer, 2) a person who worked for a client who used MPLS and although they won’t directly implement it they want someone familiar with it to support their traffic going across the MPLS, 3) someone to locally implement MPLS (and therefore my supposition from above IS wrong) or 4) they are looking for someone to continue to ‘bull’ them and tell them that they have experience when they don’t really have it?
I’m looking for opinions regarding the job economy out there. I know that you can’t know for sure what they are looking for unless you’ve placed the ad yourself. Please feel free to educate me as well if I’m making wrong assumptions. Thanks.
