OSPF supports broadcast and nonbroadcast multiaccess (NBMA), and point-to-point networks. Broadcast networks, like Ethernet, Token Ring, and FDDI, can support one, or more network attachments together with the ability to address a single message to all those attachments; a broadcast network. Alter-natively, non-broadcast networks, like X.25, ATM or Frame Relay, support one, or many hosts but do not possess a method for broadcasting. Point-to-point is exactly that, a link that has two connection points. Two routers connected together through a serial line (56k through T1) is an example of a point-to-point link. There can be no other connections in between these two points.
