Title: RE: [MPLS-OPS]: MPLS VPN implementations

Well... there is another concept, hot topic in the IETF environment, which is VPLS (Virtual Private Lan Service). What VPLS intends is to provide real any to any connectivity within a L2VPN. Nortel has a solution for VPLS now, able to provide any to any connectivity according to the Logical PE draft.

Subject: [MPLS-OPS]: MPLS VPN implementations


Dear All,

I just wanted to know the difference between a Layer 2 & Layer 3 VPN
implementation.

As far as my understanding goes

Layer2 VPN is a virtual pipe extended between 2 sites (point to point)

Layer3 VPN provides any to any connectivity for all sites (point to
multipoint / mulitpoint to multipoint)

Am I correct in my understanding?

One more scenario is that of offering TLS (Transparent Lan service). Is
this a special case of L2 VPN?

I thank everybody in anticipation of receiving these answers

Neel
