Configuring OSPF

OSPF Quick Steps

 

 

 

 

9Assign the OSPF interface to the area and the backbone using the ip ospf interface area command. For example:

-> ip ospf interface 120.1.4.1 area 0.0.0.0

or

-> ip ospf interface vlan-5 area 0.0.0.0

10 Enable the OSPF interfaces using the ip ospf interface status command. For example:

-> ip ospf interface 120.1.4.1 status enable

or

-> ip ospf interface vlan-5 status enable

11 You can now display the router OSPF settings by using the show ip ospf command. The output gener- ated is similar to the following:

-> show ip ospf
