This article explains how to configure Open Shortest Path First Configuration (OSPF). In this tutorial you will learn OSPF commands, states and OSPF authentication.The neighbor formation process in OSPF occurs in 7 stages: 1. DOWN State: After OSPF is configured, Router A will send HELLO rtrBconfigure terminal. Enter configuration commands, one per line. End with CNTL/Z. rtrB( config)router ospf 1.OSPF cannot be enabled on Router B because OSPF needs a RID and there are no IP addresses assigned on Router B. Configure the serial interfaces on Routers A and B William R. Parkhurst - Ph.D CCIE 2969. Chapter 1. OSPF Process Configuration Commands router ospf process-id Syntax Description: process-id—. The OSPF process ID. The range of values is 1 to 65535. Use the router ospf command to enter OSPF Router Configuration mode for an OSPF instance. Once you are in OSPF Router Configuration mode, you can begin configuring a new OSPF instance or change an existing configuration. Figure 2 provides an example of entering router OSPF configuration mode on R1. Note: The list of commands has been altered to display only the commands that are used in this chapter. OSPF Process ID is a unique number on this router that groups a series of OSPF configuration commands under a specific running process. Wildcard Mask: The wildcard mask (wildcardmask) given above is the inverse mask of the subnet mask. Router(config)no router rip. 2.2 Open Shortest Path First OSPF. You can modify OSPF routing by giving the next command in global configuration mode Router 2: Do the following configuration for Router 2.
