Using AH/ESP to protect ND works fine once the SA's exist.
However, there's a chicken & egg problem if you want to use IKE, and
manually configuring N*(N-1) SA's across N machines on the link is not
deployable.
So if you want to use IPsec to protect ND, you need to solve the key
management problem for ND.
