![]() OSPF responds by changing its operation to match the settings you’ve provided. Take into account its capacity to support both broadcast and non-broadcast multi-access (NBMA) network types. It requires the use of a DR/BDR relationship, and it has a 10-second hello and 40-second dead timer. It requires a link that supports Layer 2 broadcast. The broadcast network type is the default network type for an OSPF-enabled Ethernet interface. Leased lines running Point-to-Point Protocol (PPP) and High-Level Data Link Control (HDLC) are some examples of point-to-point links. It does not maintain a DR/BDR relationship, and it has a 10-second hello and 40-second dead timer. On a point-to-point link, a packet delivered from one of the routers will always have precisely one recipient. ![]() Point-to-Point to Point-to-Multipoint Networks (adjust hello and dead timers)Ī Point-to-Point network type is, as its name implies, a connection between two specific points (or OSPF routers).Broadcast to Non-broadcast Networks (adjust hello and dead timers).The following list indicates which OSPF network types can communicate with one another: Some types will function together, but the hello and dead timers must be adjusted. As a network engineer working with OSPF, you must understand the differences between each OSPF network type and their compatibility. ![]() In this article, we are going to discuss the two major network types, which are Point-to-Point and Broadcast. RFC 2328: OSPF Version 2 defines OSPF network types.
