• Enable OSPFv2 on an interface and assign a network address range to a specific OSPF area.
CONFIG-ROUTER-OSPF-id mode
network ip-address mask area area-id
The IP Address Format is A.B.C.D/M.
The area ID range is from 0 to 65535 or A.B.C.D/M.
Enable OSPFv2 on Interfaces
Enable and configure OSPFv2 on each interface (configure for Layer 3 protocol), and not shutdown.
You can also assign OSPFv2 to a Loopback interface as a virtual interface.
OSPF functions and features, such as MD5 Authentication, Grace Period, Authentication Wait Time, are
assigned on a per interface basis.
NOTE: If using features like MD5 Authentication, ensure all the neighboring routers are also
configured for MD5.
In the example below, an IP address is assigned to an interface and an OSPFv2 area is defined that
includes the IP address of a Layer 3 interface.
The first bold lines assign an IP address to a Layer 3 interface, and theno shutdown command ensures
that the interface is UP.
The second bold line assigns the IP address of an interface to an area.
Example of Enabling OSPFv2 and Assigning an Area to an Interface
Dell#(conf)#int te 4/14/1
Dell(conf-if-te-4/14/1)#ip address 10.10.10.10/24
Dell(conf-if-te-4/14/1)#no shutdown
Dell(conf-if-te-4/14/1)#ex
Dell(conf)#router ospf 1
Dell(conf-router_ospf-1)#network 1.2.3.4/24 area 0
Dell(conf-router_ospf-1)#network 10.10.10.10/24 area 1
Dell(conf-router_ospf-1)#network 20.20.20.20/24 area 2

Dell Networking recommends using the interface IP addresses for the OSPFv2 router ID for easier
management and troubleshooting.
To view the configuration, use the show config command in CONFIGURATION ROUTER OSPF mode.
OSPF, by default, sends hello packets out to all physical interfaces assigned an IP address that is a subset
of a network on which OSPF is enabled.
To view currently active interfaces and the areas assigned to them, use the show ip ospf interface
command.
Example of Viewing Active Interfaces and Assigned Areas
Dell>show ip ospf 1 interface
TenGigabitEthernet 1/17/1 is up, line protocol is up
