Basic OSPF Configuration
Configuring a Loopback Address
Modifying OSPF router Priority
Propagating a Default Route
Verifying the OSPF Configuration
Enable OSPF on the router using the following command syntax:
router(config)# router ospf process-id
The process ID is a process number on the local router. The process ID is used to identify multiple OSPF processes on the same router. The number can be any value between 1 and 65,535. You do not have to start numbering OSPF processes at 1. Most network administrators keep the same process ID throughout the entire AS.
Identify IP networks on the router using the following command syntax:
router(config-router)# network address wildcard-mask area area-id
router(config)# router ospf process-id
The process ID is a process number on the local router. The process ID is used to identify multiple OSPF processes on the same router. The number can be any value between 1 and 65,535. You do not have to start numbering OSPF processes at 1. Most network administrators keep the same process ID throughout the entire AS.
Identify IP networks on the router using the following command syntax:
router(config-router)# network address wildcard-mask area area-id
Configuring a Loopback Address
router(config)# interface loopback number
router(config-if)# ip address ip-address subnet-mask
Example 3-1
router(config)# interface loopback0
router(config-if)# ip address 192.168.1.1 255.255.255.255
router(config-if)# ip address ip-address subnet-mask
Example 3-1
router(config)# interface loopback0
router(config-if)# ip address 192.168.1.1 255.255.255.255
Modifying OSPF router Priority
router(config-if)# ip ospf priority number
Example 3-2 Setting e0's Priority
RTB(config)# interface e0
RTB(config-if)# ip ospf priority 0
Example 3-2 Setting e0's Priority
RTB(config)# interface e0
RTB(config-if)# ip ospf priority 0
Propagating a Default Route
Router (config)#ip route 0.0.0.0 0.0.0.0 [interface | netst-hop address]
To propagate this route to all the routers in a normal OSPF area, user the following configuration statement:
Router (config-router)# default-information originate
To propagate this route to all the routers in a normal OSPF area, user the following configuration statement:
Router (config-router)# default-information originate
Verifying the OSPF Configuration
show ip protocol
show ip route
show ip ospf interface
show ip ospf
show ip ospf neighbor detail
show ip ospf database
clear ip route*
clear ip ruote a.b.c.d
debug ip ospf
show ip route
show ip ospf interface
show ip ospf
show ip ospf neighbor detail
show ip ospf database
clear ip route*
clear ip ruote a.b.c.d
debug ip ospf
