I'm looking for some info on MPLS and people who may have gone through such a transition.
We have our own routers right now and the company that did the originally setup created VLANS on the routers themselves instead of core switches. Is this going to be a problem?
We also have IPSec/GRE Tunnels as backup routes going over our internet T1's. How does this complicate things? If they want to replace our routers with theirs will they allow us to have a tunnel created on it?
I have a meeting on Friday but wanted to learn a little bit and look for any questions that I might be able to ask them.
thanks in advance.
