[nsp] REG: MPLS based VPN's

Hi All,
We are in the process of provisioning MPLS on an packet only (IP) based
infrastructure, primarily to cater to corporate VPN requirements. My
questions are as follows -
1. By provisioning an MPLS based VPN can I commit bandwidth guarantees to
my VPN customers (something like Frame Relay CIR).
2. I have read that MPLS VPN's seperate the Internet routing tables from
customer routing information. When a VPN is provisioned for a customer,
how does the routing actually happen? The customer would prefer to run his
own routing protocol between his sites, & how does a service provider
provision this.
3. I have come across an offering from AT&T, called Frame over IP, wherein
customers connect using Frame Relay & eventually get hooked on to an IP
(MPLS) cloud, which is the core of the AT&T network. Any comments on this.
Kindly advice,

With warmest regards,
