The linked document talks about issues with using private IP addresses. I
am not suggesting that you do that. I am suggesting that you use _no_ IP
addresses on the links. Generally the devices will use the loopback IP,
which will be public, for your traceroutes and for ICMP.

None of the issues in RFC 6752 are applicable to the concept of using host
routes to peer loopback address instead of assigning link specific
addressing.

Baldur
