  1. Figure 1 OSPF on Cisco ASA.
  2. R2#configure terminal.
  3. R2(config)#interface Loopback0.
  4. R2(config)#router ospf 1.
  5. R3#configure terminal.

How OSPF configure OSPF?

Configuring OSPF in a Single Area

  1. Use the command router ospf process ID to start OSPF.
  2. Use the network command to enable the interfaces.
  3. Identify area assignments.
  4. (Optional) Assign the router ID. Example 3-1 displays OSPF with a process ID of 1 and places all interfaces configured with an IP address in area 0.

How do I find OSPF configuration?

To display general information about Open Shortest Path First (OSPF) routing instances, use the show ip ospf command. Use the show ip ospf command to display information about one or more OSPF instances. This command requires the LAN Base Services license.

Which command will verify that a router that is running ospfv3 has formed an adjacency with other routers in its OSPF area?

The show ip ospf neighbor command is used to verify that the router has formed an adjacency with its neighboring routers.

What is OSPF example?

A simple two-router OSPF network Here’s an example of a network configuration that creates a very simple OSPF network between two Cisco routers. The routers are placed in area 0 and an OSPF point-to-point link is configured between them. R1 will announce the 1.1. 1.1/32 route and R2 will announce 2.2.

Is it possible to configure OSPF over tunnel interface?

To run OSPF over IPSec tunnels, a Layer 3 GRE tunnel is configured between two routers with GRE destination addresses as the inner address of the IPsec tunnel. OSPF is enabled on the Layer 3 GRE tunnel interface, and all of the OSPF control packets undergo GRE encapsulation before entering the IPsec tunnels.

What are the different configurations of OSPF?

OSPF Non-Broadcast Network Type.

  • OSPF Broadcast Network Type.
  • OSPF Point-to-Multipoint Network Type.
  • OSPF Point-to-Multipoint Non-Broadcast Network Type.
  • OSPF Point-to-Point Network Type.
  • OSPF Next Hop with Network Types.

    • What is OSPF configuration?

    OSPF basic configuration is very simple. Just 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.

    What port does OSPF use?

    89 port number
    Difference between OSPF and BGP

    S.NO OSPF
    6. In OSPF internet protocol is used.
    7. It works in 89 port number.
    8. OSPF is a Link State type.
    9. In OSPF Dijkstra algorithm is used.

    Which three features are of OSPF routing protocol?

    OSPF bases link cost on bandwidth to determine the best route. OSPF is a distance vector type of protocol. OSPF uses DUAL algorithm for route computation. OSPF updates are event triggered.

    How OSPF works step by step?

    How does OSPF work?

    1. There are three steps that can explain the working of OSPF:
    2. Step 1: The first step is to become OSPF neighbors.
    3. Step 2: The second step is to exchange database information.
    4. Step 3: The third step is to choose the best route.

    What is the administrative distance of OSPF?

    110
    The range for administrative distance is 0–255. The default value is 120 for RIP routes and 110 for OSPF routes.

    Which layer is OSPF?

    OSPF and BGP belong to the Application Layer.
