OSPFv2
OSPFv2 supports IPv4 address families. OSPFv2 routers initially exchange hello messages to set up adjacencies with neighbor
routers. The hello process establishes adjacencies between routers of the AS. It is not required that every router within the
AS areas establish adjacencies. If two routers on the same subnet agree to become neighbors through this process, they begin
to exchange network topology information in the form of LSAs.
In OSPFv2, neighbors on broadcast and non-broadcast multiple access (NBMA) network links are identified by their interface
addresses, while neighbors on other types of links are identified by router-identifiers (RID).
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 instance-number
2. Enter the interface information to configure the interface for OSPF in INTERFACE mode.
interface ethernet node/slot/port[:subport]
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 ip-address/mask
6. Enable OSPFv2 on an interface in INTERFACE mode.
ip ospf process-id area area-id
● process-id—Enter the OSPFv2 process ID for a specific OSPF process, from 1 to 65535.
● area-id—Enter the OSPFv2 area ID as an IP address (A.B.C.D) or number, from 1 to 65535.
