Your understanding is correct.

Layer 2 VPNs are a point to point link between 2 points while Layer 3 VPNs can provide any to any connectivity. For example using MPLS based IP VPN service is an example of a Layer 3 VPN.

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
