OSPF Process Configuration Commands router ospf process-id Syntax Description: process-id—. The OSPF process ID. The range of values is 1 to 65535. 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. 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. The shutdown command in the config>router>ospf>interface context can be used to disable an interface without removing the configuration for the interface. no interface — No OSPF interfaces are defined. Configuration is as simple as defining the OSPF process using the router ospf command, and then identifying the networks that will participate in OSPF routing. The following table lists the commands and details for configuring OSPF . D(config) router ospf 1 D(config-router) network 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. Command Modes Exec > Global Configuration > Context Configuration > OSPF Configuration configure > context contextname > router ospf Entering the above command sequence results in the following prompt: [local]hostname(config-ospf ) Open Shortest Path First (OSPF) is an interior gateway protocol (IGP) used to exchange routing information between routers within a single autonomous system (AS).When you do initial configuration, set the router ID. You can also use the following commands to change the router ID. In this site you can find Computer tips,cisco router configuration, routing protocols, switch configuration and accesslist configuration with step by step commands. subnet calculator help you to do easy subnetting.you can download packet tracer andOSPF Configuration.

Router(config) router ospf process-id.Enables OSPF routing, which places you in router configuration mode. Defines an interface on which OSPF runs and define the area ID for that interface. Use the commands in this chapter to congure and monitor the Open Shortest Path First (OSPF) routing protocol.To enable authentication for an OSPF area, use the area authentication router conguration command. To configure the router to send a syslog message when an OSPF neighbor goes up or down, use the following command in router configuration mode To configure an Open Shortest Path First (OSPF) routing process, use the router ospf command in global configuration mode.This example shows a basic OSPF configuration using the router ospf command to configure OSPF VPN routing and forwarding (VRF) instance processes for the VRFs Router(config)no router rip. 2.2 Open Shortest Path First OSPF.

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. To configure an Open Shortest Path First (OSPF) routing process, use the router ospf command in global configuration mode.[28]. 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 Simple OSPF configuration. The following example illustrates how to configure single-area OSPF network. Lets assume we have the following network.Cisco Router Basic Configuration. OSPF Configuration Commands.

Configuration Examples. ! To configure MD5 authentication for OSPF area 1, run the following command: Switch(config-router-ospf)area authentication message-digest ! Figure 1 Configuring OSPF. The router ospf command entered in global configuration mode with autonomous-system-number argument creates an OSPF routing instance. This command is executed in OSPF router configuration mode to statically configure a router id on a specific neighbor. show ip ospf proc-id.

Configuration. Lets start with all network commands to get OSPF up and running. The network command defines to which area each interface will belong.First, we will configure R1 and R2 for the backbone area: R1(config)router ospf 1 R1(config- router)network area 0. 244 Chapter 7: Configuring OSPF in a Single Area Table 7-8 Explanation of the show ip ospf interface Command (Continued).The show ip protocols Command This command shows the conguration of IP routing protocols on the router. Display VTYSH command prompt. configure terminal. Enters global configuration mode. router OSPF.
