What are the steps to configure OSPF?
Procedure
- Set the global configuration options.
- Set the OSPF router ID, if the OSPF protocol is used.
- Define OSPF areas, if the OSPF protocol is used.
- Limit information exchange between OSPF areas, if the OSPF protocol is used.
- Define IPv4 interfaces, if the IPv4 OSPF or IPv4 RIP protocol is used.
How do I find the OSPF configuration on my router?
There are several ways to verify OSPF configuration and operations, which are:
- show ip route command.
- show ip ospf command.
- show ip ospf database command.
- show ip ospf interface command.
- show ip protocol command.
- show ip ospf neighbor command.
- debugging ospf.
How OSPF configure OSPF?
Configuring OSPF in a Single Area
- 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. Example 3-1 displays OSPF with a process ID of 1 and places all interfaces configured with an IP address in area 0.
Which command is used to configure OSPF?
The router ospf process-id command is the beginning of any Cisco IOS OSPF configuration. It is used to create or modify an existing OSPF routing process and enters the user into OSPF router configuration mode.
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.
Which two commands are required for basic OSPF configuration?
Which two commands are required for basic OSPF configuration? Explanation: The “Router ospf [process-id]” command enables OSPF routing protocol in the router and the “[Wildcard-mask] area [area-id]” command is used to select the interfaces that we want to include in the OSPF process.
How do I find my OSPF router ID?
If the router is already configured for OSPF, you may want to use the router ID that is already in use on the router rather than set a new one. To display the router ID, enter the show ip command at any CLI level or select the IP->General links from the Configure tree in the Web Management Interface.
How can I check my OSPF status?
To display OSPF link state information, enter show ip ospf link-state at any CLI level. Displays the hexadecimal data in LSA packets (advertisements) for the OSPF areas configured on the routing switch. The output can also be filtered by area ( area-id ), link-state-id , router-id , sequence-number , and/or type .
How will you configure OSPF in an interface?
Step-by-Step Procedure
- Configure the interface. [edit]user@host# set interfaces at-0/1/0 unit 0 family inet address 192.0.2.2.
- Create an OSPF area. [edit]user@host# edit protocols ospf area 0.0.0.1.
- Assign the interface to the area and specify the neighbor.
- If you are done configuring the device, commit the configuration.
What is Area ID in OSPF?
An OSPF area is a logical grouping of routers sharing the same 32-bit Area ID. The Area ID can be expressed in dotted decimal notation similar to an IP address, such as 192.168. 17.33. The Area ID can also be expressed as a decimal equivalent, so Area 261 is the same as Area 0.0.
What is OSPF ID?
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. OSPF Router ID should not be changed after the OSPF process has been started and the ospf neighborships are established.
