Re: Layer 2 Transport

[Jeff Behrns via NANOG <nanog () nanog org>]

Identify L2 control protocols which will require transparent tunneling end to end before making a decision on underlay 
tech.  Beware of multiple vendor handoffs / NNIs under the hood of any solution, but especially an "oMPLS" solution.

We use mainly mpls/p2p pw so much for wholesale/business Ethernet, CBH, and various other purposes.  Still using 
mpls/vpls occasionally… oob mgmt backhaul.  For DC interconnect, I use evpn/mpls, since I have an mpls network.  We are 
an SP, so mpls has been the basis for our network-based-L2/L3 VPN’s for 10 years or so.

What technologies are predominately in use today to transport layer 2 circuits?

MPLS\VPLS used to be all the rage.
eVPN\VXLAN seems to be popular in the datacenter space.
Carrier Ethernet?
