Enable OSPFv2

OSPFv2 is disabled by default. Configure at least one interface as either physical or LOOPBACK and assign an IP address to the interface. You can assign any area besides area 0 a number ID. The OSPFv2 process starts automatically when you configure it globally and you can enable it for one or more interfaces.

  1. Enable OSPF globally and configure an OSPF instance in CONFIGURATION mode.
    router ospf 
  2. Enter the interface information to configure the interface for OSPF in INTERFACE mode.
    interface ethernet 
  3. Enable the interface in INTERFACE mode.
    no shutdown
  4. Disable the default switchport configuration and remove it from an interface or a LAG port in INTERFACE mode.
    no switchport
  5. Assign an IP address to the interface in INTERFACE mode.
    ip address 
  6. Enable OSPFv2 on an interface in INTERFACE mode.
    ip ospf
