What is router OSPF 1?
All routers are in OSPF Area 0. I need to use the router ospf command to get into the OSPF configuration. The number “1” is a process ID and you can choose any number you like. It doesn’t matter and if you want you can use a different number on each router.
How do I manually configure an OSPF router ID?
If you want to change the router ID setting, do the following:
- Go to the global config context; the CLI prompt appears similar to the following:
- If OSPF is not enabled, go to Step 3; if OSPF is enabled, use no router ospf to disable OSPF operation.
- Use ip router-id ip-addr to specify a new router ID.
What is router OSPF command?
Configure OSPF Routing Daemon The area variable can be typed in two formats: [W.X.Y.Z]; or as an integer [Z]. area [Z] range [A.B.C.D/M] Create area 0.0.0.Z and set a classful network for the area (range and interface network and mask setting should match)
How do I find my OSPF config?
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.
What is OSPF configuration?
Configuring OSPF 1 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. Next, you need to define on which interfaces OSPF will run and what networks will be advertised.
How is OSPF router ID determined?
The OSPF Router ID is used to provide a unique identity to the OSPF Router. OSPF Router ID is an IPv4 address (32-bit binary number) assigned to each router running the OSPF protocol. If there is no Loopback Interfaces configured, the highest IP address on its active interfaces is selected as the OSPF Router ID.
What are the router types in OSPF?
Four Types of OSPF Routers
- Routers for internal use: Internal routers. Internal routers are routers that belong to the same OSPF region as their directly connected networks.
- Area Borders Routers.
- Autonomous Systems Boundary Routers.
- Backbone Routers.
How do I enable OSPF on my router?
To enable OSPF on a Cisco router and advertise interfaces, the following tasks are required:
- Use the command router ospf process ID to start OSPF.
- Use the network command to enable the interfaces.
- Identify area assignments.
- (Optional) Assign the router ID.
What is OSPF process ID?
The process ID is the ID of the OSPF process to which the interface belongs. The process ID is local to the router, and two OSPF neighboring routers can have different OSPF process IDs.

How to configure OSPF?
Identify the network interfaces that should run OSPF.
When to use OSPF?
OSPF is used in larger networks in larger orgnizations where topology and devices can all use OSPF (most of them) but there is no way to manage so many devices (imagine defining routes in every system when you have 100s or 1000s). So OSPF helps here by handling outage to a certain extent.
