Hello

A client who has a HO and several branches with IPSEC VPN's between the routers.

So he is asking for The performance of Layer 2 versus layer 3 Encryption and which is better to implement,

My questions is what are the types of L2 encryption that could be done on a VPN and is better then L3 encryption?

Georges, good question .. there are various scenarios where L2 and L3 encryption architecture are implemented, indeed each one has advantanges and disadvantages over each other but each must be chosen based on WAN/MAN architectures.

It seems to me your client currently have ipsec tunnels in a hub and spoke setup, are the links private lease lines? or are the links regular internet links going via public network, if regular internet links Ipsec L3 encryption is the choice, private leased lines are the most common candidates for l2 encryption.

this link tells you more in details
