I am a complete newbie to MPLS so please bear with me as I get to learn a little about the set of protocols.
Here is our situation. We have a channalized DS3 for internet access, and we just aquired a smaller company. Right now we have a site-to-site IPSEC tunnel with them and eventhough that is working fine, I want to have alternatives to scaling our network when it comes to remote offices. So the first thing I thought of were MPLS VPNs. I have read they scale well because goes away from the hub and spoke model to a any-to-any model. I like that.
So my questions are:
1. Can I peel off a channel of my DS3 to use for my end of the MPLS tunnel?
2. My counterpart in the remote office would then have to get some telco circuit with the same Provider correct?
3. We are putting in VOIP solution here at the main office that we want to use company wise. Does that change the kind of MPLS solution we need to implement.
4. Having said what I have said so far, does MPLS sound like the right fit? We are a growing company and I assume having more remote offices will continue.
Thanks for any help or advice you can give,
