In this example we have two OSPF areas — area 0 and area 1.

Configuration du routage ospf – routeur Cisco

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. Area IDs are unique numeric identifiers, in dotted decimal notation.

Confirm your configuration by entering coonfiguration show protocols ospf command. OSPF basic configuration is very simple. You must also create a backbone area if your network consists of multiple areas. We can verify that the routers have become neighbors by typing the show ip ospf neighbors command on either router:.

Example: Configuring a Single-Area OSPF Network – TechLibrary – Juniper Networks

We will use the following network topology:. R3 is in the area 1. This can be done by using the following sequence of commands on both routers:. Now R2 should have neighbor relationship with both R1 and R3.

The network commands entered on both routers include subnets directly connected to both routers. Jan 26, upravnik. To quickly configure a 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, and then enter commit from configuration mode.

Example: Configuring a Single-Area OSPF Network

As you can see from the network configuratoon depicted above, routers R1 and R3 are in the area 0 and area 1, respectively. NOTE We have used the router-id 1.

Characters IA in front of the routes indicate that these routes reside in different areas. Next, you need to define on which interfaces OSPF will run and what networks will be advertised. Home About Contact Support our work.

We can do that using the following sequence of commands:. Confirm that the Area field displays the value that you configured.

For example, here is the output of the command on R Because R1 connects only to R2, we only need to establish a neighbor relationship with R2 and advertise directly connected subnet into OSPF.

Our goal is to advertise the subnets directly connected to R1 and R3. To confirm your OSPFv3 configuration, enter the show protocols ospf3 command. To verify if the routing updated were exchanged, we can use the show ip route command.

To do that, we need to specify different area ID for each neighbor relationship, 0 for R1 and 1 for R2. In an autonomous system ASthe backbone area is always assigned area ID 0.

Confighration a single-area OSPFv3 network, include the ospf3 statement at the [edit protocols] hierarchy level. Configuration of R3 looks similar, but with one difference, namely area number. If the output does not display the intended configuration, repeat the instructions in this example confiburation correct the configuration.

To verify if directly connected subnets are oospf advertised into the different area, we can use the show ip route ospf command on both R1 and R Then we need to define what network will be advertised into OSPF. Configure the device interfaces. Area IDs need only be unique within an AS.

To do that, the following configuration on R1 will be used:. First, we need to enable OSPF on both routers. We can verify that by using the show ip ospf neighbor command:. Configure the router identifiers for the devices in your OSPF network.
