OK I am learning the theory of MPLS and have setup in GNS3 an MPLS core with 6 routers and 2 customers with 2 sites each in separate VRF's so am comfortable with the technology.
What I am not sure on is the real world implementation of it.
The ISP currently has 8 customers 1 is 500 customers across 3 sites, others are 50 users in 2 sites and a few are single sites. All run P2P links into the data centre and aggregate on a 3560 switch, which then routes to an ASA for internet.
The client wants to run an MPLS core, and I am just trying to work out if this is overkill for the size of the company at the moment?
They want to spec it up for future growth, but only run a single site. My question is scaling the options up from simply implementing separate vrf's on the 3560 per customer (The reason so they can run the same address space?)
I just can't figure how you would implement a topology such as this
Into a single site data centre, would a topology like this span across multiple sites? Or would it all live in the same rack?
Would the PE's be 6500's and P routers be 3825's or better?
I just cannot find anything on the internet that covers a real world design of an MPLS core that actually covers hardware.
I understand this question is like how long is a piece of string, but taking the topology in the link above as an example what hardware would you use for this? And where geographically would the routers sit?
Hi Everyone, Would like to extend my thanks in advance for anyone offering assistance. As the subject hints, anyone here know of a way to convert IOS configs to XR config? I seen and heard about SOX tool but i am unable to find it. I also tried ...

Symptoms: the root password can't log in by GUI Solution:1) login CLI as admin2) write command "ncs webroot enable" without qutations3) we can check the status by "ncs webroot status" hope this will help someonethanks
ISO images are as close as we can get to the old school classic IOS images from back in they day.
Doing upgrades by putting a new image on the flash, changing the boot pointer and reload was and is still the walhalla of Cisco based devices.
