Hi,

Benefit of MPLS over traditional P-to-P

is off course a cost. But apart from cost what are techonoloical benefits of having MPLS over leased links. Is'nt MPLS less secure as compared to leased circuit.

In a nutshell what are convincing factor for MPLS over P-to-P leased line.

Sounds too basic :)

Any link on cisco.com or any other is appreciated.

Thanx in advance

MPLS VPN's have a direct comparision to other shared access media VPN's like Frame Relay ATM etc. It cant be compared directly to a P2P Private Circuit.

Here is a link comparing MPLS VPN sec to FR and ATM.

Having said that it does not mean there are no loopholes in P2P private circuit and it is completely secure. Looking at the economy and the security provided by MPLS VPN's its comparable to P2P Private Circuit if not better.

But again providing MPLS based VPN;s has more benefits to the service provider that the end customer. For the customer the only major benefits is with scale more number of services would be available to him if using a MPLS VPN at lesser cost when compare to other technology based VPN;s.

Hi,

to complete the Swaroop explanation, VLL are L2 services that as Customer you could have over MPLS network, and not with a traditional leased line:
