Hi all, it is just my curiousity that ended up with a small discussion like this. Here's about it...
My company has a main client which have tonnes of remote sites connecting to both their HQ and Disaster Recovery Centre. Some of the remote sites still running on frame-relay, while other is purely leased-line. There's a few question I wish I can clear up as follows:
i. When the client have frame-relay device, what we do is create a tunnel and route all the frame-relay traffic over. Is there any advantage if we change it over to MPLS?
ii. Even if comparing to leased-line services, what kind of advantages I can expect if our cliet migrate over to leased-line?
iii. If one customer is running purely on frame-relay connectivity, any difficulties will arise when they want to switch over to MPLS network?
I still never has any hands on experience on the MPLS, that's why need to gather some info in the first place, I'm currently have a glance through those MPLS guides and configuration examples, but I knew that perhaps in real-life network, things may differs, in the meanwhile I'm studying through it, hope to gather some precious opinions.
