Pros of MPLS

What are the Pros and Cons for implementing MPLS on a local LAN? I've gone through MPLS in my CCNP studies and MPLS is used mostly on service provider networks. I run a network of 3000 PC's a 2500 IP phones spread across a medium size city with 90% of my locations connected by fiber, what benefits would i gain by implementing MPLS?

Re: Pros of MPLS

There is no reason that I can think of for why you would want to run MPLS in your local LAN.

Re: Pros of MPLS

I should add I have a physically separated network for the Public Library, would MPLS allow me to securely combine this network with the larger internal employee network cutting my equipment cost?

Re: Pros of MPLS

Maybe. What is your security policy? Is it OK that you peer your network an ISP? What are your bandwidth requirements? Would a point-2-point T1 circuit be enough? What is the distance between the two networks? Could you run fiber to connect them?

Re: Pros of MPLS

my security policy doesn't address peering with an ISP i would have to say no if there no real need, secondly internal bandwidth requirements range based on who you ask. 1 gig between buildings has served well so far, and the answer to the last question yes the two networks are close so i could connect them with fiber.

Re: Pros of MPLS

I would connect them via fiber; high bandwidth, no ISP involvement, better security options, low interference, etc.

Re: Pros of MPLS

so connect the networks and seprate them with a ASA of a simple router, and secure with ACLs? i would need to readdress one of the network at that point right?

...Just a recap MPLS is a NO_GO too.

Re: Pros of MPLS

No to MPLS. A firewall is a good idea. If you have overlapping address space, you could either re-address as you mentioned or use NAT on the firewall.
