IN ROUTER1. And then under router OSPF configuration mode we see a 1. Is that an autonomous system number?That gets us into router configuration mode for OSPF and there are few commands we need to know. The MAX acts as an OSPF internal router with limited border router capability. At this release, we do not recommend an area border router (ABR) configuration for the MAX, so the Ethernet interfaceThe terminal server command-line interface provides commands for monitoring OSPF in the MAX. STEP 3 Now that loopback interfaces are configured, configure OSPF. Use the following commands as an example to configure each routerAgain, OSPF routers do not communicate unless certain configurations match. However, you can specify neighbors with the neighbor router configuration command, in which case you should specify a cost to that neighbor. Before the point-to-multipoint keyword was added to the ip ospf network interface configuration command, some OSPF Identify and apply the basic OSPF configuration commands. Describe, modify and calculate the metric used by OSPF. Describe the Designated Router/Backup Designated Router (DR/BDR) election process in multiaccess networks. Configuration Examples. ! To configure MD5 authentication for OSPF area 1, run the following command: Switch(config-router-ospf)area 0.0.0.1 authentication message-digest ! Open Shortest Path First (OSPF). Step 1: Enter privileged EXEC mode: Router>enable password. Step 2: Enter the configure terminal command to enter global configuration mode. 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. Configure OSPF Routing.R2>enable R2configure terminal Enter configuration commands, one per line. End with CNTL/Z. R2( config)router ospf 1 R2(config-router)network 192.168.10.0 0.0.0.255 area 0 R2 Learn how to configure an Open Shortest Path First Router-ID on a Cisco router which is used to uniquely identify an OSPF router in an autonomous system.This command is executed in OSPF router configuration mode to statically configure a router id on a specific neighbor. D(config) router ospf 1 D(config-router) network 10.10.13.0 0.0.0.255 area 0 D( config-router) end D copy running-config startup-config.Now it is time to verify our configuration. Some of the verify commands screenshot s are given below for our topology. On Router A, verification OSPF basic configuration is very simple. Like with other routing protocols covered so far (RIP, EIGRP) first you need to enable OSPF on a router. This is done by using the router ospf PROCESS-ID global configuration command. After the basic ospf configuration is done,check the adjacency formation with commands sh ospf neighbor sh ospf interface.
Link ID field contains the router ID of the adjacent peer,an OSPF router always forms an adjacency over a point-to-point link using an unnumbered interface. Open Shortest Path First (OSPF). Step 1: Enter privileged EXEC mode: Router>enable password. Step 2: Enter the configure terminal command to enter global configuration mode. Use this command to configure OSPF routers interconnecting to NBMA networks. Use the no parameter with this command to remove a configuration.

A number of different Cisco IOS OSPF configuration commands are available, but at its most basic, OSPF configuration uses three commands: the router ospf, network, and router-id commands. This release of ArubaOS Mobility Access Switch supports all Open Shortest Path First (OSPF) area types including Totally Stubby Area (TSA) and Not-So-Stubby-Area (NSSA). The following new commands are added to the Command Line Interface (CLI). In the configuration mode, type router Configure an OSPF routing process and enter router configuration mode. Specify an OSPF neighbor and optionally assign a cost to the neighbor.On point-to-multipoint networks, to prevent flooding of OSPF LSAs, use the following command in router configuration mode The following figure displays the OSPF configuration commands on Router1.To verify and test the OSPF configuration, execute the following commands on any router and review the output of each command. Figure 1 Configuring OSPF. The router ospf command entered in global configuration mode with autonomous-system-number argument creates an OSPF routing instance. It is the first step in configuring OSPF on a router as done here on R1 How to remove OSPF configurations settings from a router? Router(config)no router ospf command do that job. R1configure terminal Enter configuration commands, one per line. To enable OSPFv3 globally, enter the following command: ProCurveRS(config -ospf-router)ipv6 router ospf ProCurveRS(config-ospf6-router) After you enter this command, the HP device enters the IPv6 OSPF configuration level, where you can access several commands that allow you to View the running-config and look for this OSPF configuration for the area in questionYou can verify that traffic can reach its destination by applying the route map to router traffic with this global configuration mode context command To create or modify a routing configuration file, you must use the correct routing commands.set router ID for OSPF manually router determines its own ID if not set. ospf rfc1583compatibility.
