To verify if the routing updated were exchanged, we can use the show ip route command. Configure the device interfaces. Area IDs need only be unique within an AS.

Area IDs are unique numeric identifiers, in dotted decimal notation. Characters IA roktage front of the routes indicate that these routes reside in different areas. In an autonomous system ASthe backbone area is always assigned area ID 0. All other networks or areas in the AS must be directly connected to the backbone area by area border routers that have interfaces in more than one area.

Jan 26, upravnik. To do that, we need to specify different area ID for each neighbor relationship, 0 for R1 and 1 for R2. This can be done by configuratjon the following sequence of commands on both routers:. Then we need to define what network will be advertised into OSPF. For a single-area OSPFv3 network, include the ospf3 statement at the [edit protocols] hierarchy level. Now R2 should have neighbor relationship with both R1 and R3. Comfiguration goal is to advertise the subnets directly connected to R1 and R3.


If the output does not display the intended configuration, repeat the instructions in this example to correct the configuration.

OSPF configuration

We can verify that by using the show ip ospf neighbor command:. NOTE We have used the router-id 1. We will use the following network topology:. The network commands entered on both routers include subnets directly connected to both routers. Confirm your configuration by entering the configuratkon protocols ospf command.

To do that, the following configuration on R1 will be used:. For example, here is the output of the command on R To verify if directly connected subnets are really advertised into the different area, we can use the show ip route ospf configruation on both R1 and R In this example we have two OSPF areas — area 0 and area 1.

You must also create a backbone area if your network consists of multiple areas. To confirm your OSPFv3 configuration, fonfiguration the show protocols ospf3 command. Configure the router identifiers for the devices in your OSPF network. First, we need to enable OSPF on both routers. Confirm that the Area field displays the value that you configured.


R3 is in the area 1. Configuration of R3 looks similar, but with one difference, namely area number.

Home About Contact Support our work. As you can see from the network topology depicted above, routers R1 and R3 routagf in the area 0 and area 1, respectively. We can verify that the routers have become neighbors by typing the show ip ospf neighbors command on either router:. Because R1 connects only to R2, we only need to establish a neighbor relationship with R2 and advertise directly connected subnet into OSPF.

We can do that using the following sequence of commands:. To quickly configure rouatge single-area OSPF network, copy the following commands, paste them into a text file, remove any line breaks, change any details necessary to match your network configuration, copy and paste the commands into the CLI at the [edit] hierarchy level, cojfiguration then enter commit from configuration mode.

OSPF basic configuration is very simple. Next, you need to define on which interfaces OSPF will run and what networks will be advertised.
