I am doing the cc boot Lab 19. I am confused because I
thought that the default mode for Frame relay (pri.) interfaces was NBMA
which required you to define the neighbors. This is even listed in the
BSCN book by Paquet (p124). However, in this instance, I am not
defining neighbors in the ospf process and still establishing an
adjacency. Can someone give me a link illustrating default interface
states for OSPF?
