If the reason for L2 transport is purely customer driven and purely
ptp, then a L2 VPN solution would be better than directly transporting
the frames. If you don't have to bridge it directly, don't. Keep the
core at layer 3 wherever possible. L2 can be very hard to debug when
there are issues.

Indeed.

What we've seen is customers who prefer to manage their own IP layer,
and just need transport. These types of customers tend to be split
between EoDWDM and EoMPLS preferences. Whatever the case, their primary
requirement is control of their IP domain.

What we're not seeing anymore is l3vpn requirements, particularly on the
back of on-premise IT infrastructure moving into the cloud. We see this
driving a lot of regular IP growth.
