router ospf process-id [vrf]
Process ID is the ID assigned when configuring OSPFv2 globally.
4. Configure the area as a stub area.
CONFIG-ROUTER-OSPF-id mode
area area-id stub [no-summary]
Use the keywords no-summary to prevent transmission into the area of summary ASBR LSAs.
Area ID is the number or IP address assigned when creating the area.
Example of the show ip ospf database database-summary Command
To view which LSAs are transmitted, use the show ip ospf database process-id database-
summary command in EXEC Privilege mode.

To view information on areas, use the show ip ospf process-id command in EXEC Privilege mode.
Enabling Passive Interfaces
A passive interface is one that does not send or receive routing information.
Enabling passive interface suppresses routing updates on an interface. Although the passive interface
does not send or receive routing updates, the network on that interface is still included in OSPF updates
sent via other interfaces.
To suppress the interface’s participation on an OSPF interface, use the following command. This
command stops the router from sending updates on that interface.
• Specify whether all or some of the interfaces are passive.
CONFIG-ROUTEROSPF- id mode
passive-interface {default | interface}
The default is enabled passive interfaces on ALL interfaces in the OSPF process.
Entering the physical interface type, slot, and number enables passive interface on only the identified
interface.
– For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port[/
subport] information.
– For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port information.
– For a port channel interface, enter the keywords port-channel then a number.
– For a 40-Gigabit Ethernet interface, enter the keyword FortyGigabitEthernet then the slot/port
information (for example, passive-interface fo 2/3 ).
