This section presents you with the information you can use to configure routers that run OSPF and are connected through a point-to-point serial link with the use of HDLC encapsulation with IP addresses configured on serial interfaces. OSPF over a Point-to-Point Link with IP Addresses on Serial Interfaces Conventionsįor more information on document conventions, refer to the Cisco Technical Tips Conventions. If your network is live, make sure that you understand the potential impact of any command. All of the devices used in this document started with a cleared (default) configuration. The information in this document was created from the devices in a specific lab environment. The information in this document applies to these software and hardware versions.Ĭisco IOS ® Software Release 12.2(27) that runs on routers

For more information on OSPF routing protocol, refer to the Open Shortest Path First documentation. Readers of this document should have some basic knowledge of OSPF routing protocol. The examples explained in this document work with both HDLC and PPP encapsulations. In order to check the network type of an interface that runs OSPF, issue the show ip ospf interface command. The other network types that OSPF supports are Point to Multipoint, Broadcast, and Non-Broadcast. This document shows sample configurations for OSPF over a point-to-point link. On point-to-point links such as High-Level Data Link Control (HDLC) and Point-to-Point Protocol (PPP), Open Shortest Path First (OSPF) runs as a point-to-point network type.
