This document explains the possible causes and solutions for why the show ip ospf neighbor command reveals Open Shortest Path First (OSPF) neighbors in the init state.| Cisco
This document describes initial configurations for Open Shortest Path First (OSPF) over non-broadcast links.| Cisco
This document describes the information contained in the show ip ospf neighbor command output.| Cisco
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. This network type is enabled by default. This document shows sample configurations for OSPF over a point-to-point link. The other network types that OSPF supports are Point to Multipoint, Broadcast, and Non-Broadcast. In order to check the network type of an interface that runs OSPF, issue the show ip ospf interface command.| Cisco
This document explains a sample configuration for Open Shortest Path First (OSPF) over the broadcast medium, such as Ethernet and Token Ring.| Cisco
This document describes how to troubleshoot situations in which Open Shortest Path First (OSPF) neighbors are stuck in Exstart and Exchange states.| Cisco
