More than likely it is whenever you enable PPP you can ping the neighbor,
not authentication. When you enable PPP encapsulation the router installs a
/32 host route for the neighbor on the other side of the BRI link. It is the
/32 route that enables you to ping the directly connected neighbor and
yourself.
