Network type ospf11/2/2023 A much more efficient manner of connecting a large number of devices is to implement a multiaccess segment that is, a segment which can be accessed by multiple end points. Obviously, point-to-point links don't scale well. A packet sent from on of the routers will always have exactly one recipient on the local link. A point-to-point network is, as its name aptly describes, a link between exactly two points (or routers). This is by far the simplest network type, and serves as a convenient anchor from which to advance the discussion. OSPF addresses three classes of network (as listed in section 1.2 of RFC 2328): point-to-point, broadcast, and non-broadcast. Fortunately, working with Dynamips and virtual frame relay networks provided the experience I needed to feel comfortable implementing all the different OSPF network types. Dynamic routing protocols, particularly OSPF, demand familiarity with all sorts of layer two topologies, so I knew I had to better educate myself on the matter. Having worked almost exclusively with Ethernet transport my whole career, it took me a while to really grasp the concept of non-broadcast networks.
