That's one view.
Another perspective is that L2TP over IPsec represents an effort by
Microsoft & Cisco to preserve a joint development investment in L2TP,
irrespective of its technical merit in this context :-). If I am
sending non-IP packets, L2TP is appropriate, but if I am sending IP,
then the extra headers introduced by L2TP are not only wasteful of
bandwidth on a continuing basis, but they also interfere with the
access controls that are an essential part of IPsec. One needs some
means of dealing with bind time connection parameters, but use of
L2TP on a continuing basis is an expensive means of achieving this
goal.
