>Hi Guys,
> I need to know if any of you have implemented a
>somewhat similar scenario. ( In a lab / real
>environment )
We have implemented MPLS on our network and are delivering services to our
customers across it.
>1. Frame Relay Switches in the Core
We use ATM across the core using 7513's.
>2. P & PE router functionality fit into the same box (
>say a 7513 )
Also we have had to do P and PE functionality on one of our 7513's as some
customer connections hit the "P" router as ATM VC's. I have found this works
fine
>3. MPLS VPNS
We have deployed 7 VPN's using MPLS and have more on the way, I have found
them very simple to configure and manage, adding customers to a box or
moving existing ones is a 2 minute job.
>4. Static Configuration of routes in the PE - CE Link
>( this shud reduce the size of my VRF )and thus

When we moved the Internet into a VPN I put static default routes on the
internet facing boxes, the default is then distributed by your routing
protocol so only your Internet routers have to hold a full BGP table, this
also works very well.
>4. No TE
As yet I have not done any traffic engineering, this is next on my list.

The only thing I can see that will limit the number of MPLS VPN's is the
size of the routing tables you have within the VRF's, which will obviously
be limited by RAM.
I hope this answers your questions, build your MPLS network and never look
back:)
