OSPF Media Support

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.

OSPF Media Support

  Broadcast—Networks such as Ethernet, Token Ring, and FDDI.
  Non-broadcast Multiaccess (NBMA)—access that does not support broadcast but allows for multiple station access such as ATM, Frame Relay, and X.25.
  Point-to-Point—Links that only have two network attachments, such as two routers connected by a serial line.
