The examples I've seen/heard of for Internet connectivity utilize a separate
VPN (like VPN 0) for internet stuff... That would depend on how you wanted
to set that up as a service provider. Most likely, you'd have a different
VC (ATM, frame or whatever) in order to do NAT on the customer end when
connecting to the internet... Just a thought.
Dial up customers are indeed a problem. The better thing to do would be to
do L2TP, where you can tunnel the dial up users back to the CE router to
assign an IP and handle all the PPP termination stuff, therefore for your
VPN traffic, IP is IP...
You can run OSPF, RIP or whatever you want between the PE and CE routers...
I guess for sanity's sake, I would highly recommend using someting OTHER
than a classful routing protocol (like RIP or IGRP). I would think that
static routes would be a much better solution for stability's sake.

Subject: RE: [nsp] REG: MPLS VPN route exchange
Hi All,
Thanks a lot for all the guidance, & help extended to me. Its really been a
great experience interacting with all of you. Just a few more queries,
Kindly help me out.
I understand that the VRF table decides the list of destinations that are
allowed to be accessed by a particular VPN customer's network. Now if the
same customer needs Internet access, How will it provisioned, will it be
achieved by a default route at the customer end. But there is always a
possibility that a customer part of another VPN could be using a global
address space say something like "206.103.12.0" in his internal network,
How will such a case be addressed if the customer with Internet access
directs a packet to an Internet site addressed with "206.103.12.0".
If I want to cater to a group of Dial-up customers to access a Corporate
Intranet site using MPLS, How will it be achieved, I understand that there
could be no VRF associated with a Dial-up port.
Is it not possible to run OSPF with a MPLS VPN customers ie between PE -
CE.
Assume that I run RIP with three customers being part of different VPN's,
The RIP routing table of customer routes will be common. How will I ensure
that certain RIP routes of a particular customer will be part of only his
VRF.
Kindly advice
Thanks & Kind regards,
Vinod.
