What is the command to enter OSPF configuration prompt?
What is the command to enter OSPF configuration prompt?
Router#configure terminal Command is used to enter in global configuration mode. Router(config)#interface serial 0/0/0 Command is used to enter in interface mode.
How do I 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.
How can I tell if Cisco OSPF is working?
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.
How do I find my ospf database?
You can use one of three commands to see you own LSA-1:
- show ip ospf database router self-originate.
- show ip ospf database router 1.1. 1.1.
- show ip ospf database router adv-router 1.1. 1.1.
What command displays the ospf section of the running configuration?
The show ip ospf database command can be used to display the OSPF LSDB. The show ip route [ospf | subnet mask] command can be used to display OSPF routes in the current routing table. The show ip protocols and show ip ospf interface [brief] commands can be used to display which areas are configured on a device.
What is OSPF algorithm?
Open Shortest Path First (OSPF) is a link-state routing protocol that was developed for IP networks and is based on the Shortest Path First (SPF) algorithm. OSPF is an Interior Gateway Protocol (IGP).
How does OSPF work in Cisco?
What is OSPF and How Does it Work? When configured, OSPF will listen to neighbors and gather all link state data available to build a topology map of all available paths in its network and then save the information in its topology database, also known as its Link-State Database (LSDB).
How many tables are there in OSPF?
The OSPF process builds and maintains three separate tables: • A neighbor table – contains a list of all neighboring routers. A topology table – contains a list of all possible routes to all known networks within an area. A routing table – contains the best route for each known network.
