/127 between routers?

[Xavier Beaudouin]

Hi there...

I can't figure if there is any drawback to use a /64 and subnet it into
/127 only for point to point connections between routers.

Seems that OpenBSD doesn't forbid that, but I wanted to know if there is
any drawback in this way of connection each routers in such way.

When I was working on 2000 and have 6bone stuff and was pTLA, we cannot do
that, now KAME stack on OpenBSD allow that.

Any good practices in this domain ?
