Apparently the maintainer of the PPP primer has changed addresses or
something. I found his use of 127.x.x.x addr's to be a source of
trouble on 4.6 and I wanted to tell him so.
OK, well a formal doc-pr I guess will follow.

Hi,
FreeBSD recently made 127.x.x.x addresses entirely local in order to
comply with some RFC someone found as well as some firewall software
users wanted to use. The issue was that traffic to 127.x.x.x addr's
should not leave the machine ever.
This makes the 127.x.x.x numbers very bad to use as bogus addr's in
the PPP primer. I just tried out PPP with a conf in which
set ifaddr 127.1.1.1/0 127.2.2.2/0 255.255.255.0
add 0 0 127.2.2.2
and got some very nasty messages about routes already existing and other
weirdness when I tried using PPP. The dialup connection would occur, but
I could not ping anything, even by IP addr.
I changed the lines to
set ifaddr 10.1.1.127/0 10.2.2.127/0 255.255.255.0
add 0 0 10.2.2.127
And everything worked fine. I think your primer needs to use better fake
addr's.
If you want me to write a formal PR for this I will. Or if you no longer
maintain the PPP primer, I'll see what I can do to get something committed.
BTW PPPPP was an excellent resource when I was first setting up my
home network. Thanks.
