Nevermind, I just found the answer to my question. In IOS, if you add
authentication to the interface it only authenticates the hello
packets. If you add authentication to the routing instance, it
authenticates LSPs but not hellos. If you want everything to be
authenticated you have to configure authentication on the interface
and on the routing instance.
