Enabling and Disabling Summarization
Summarization can also be enabled or disabled when creating an area. Enabling summarization allows for
ranges to be used by Area Border Routers (ABRs) for advertising routes as a single route rather than
multiple routes, while disabling summarization prevents set ranges from functioning in stub and NSSA
areas. (Configuring ranges is described in
For example, to enable summarization for Area 1.1.1.1, enter the following:
-> ip ospf area 1.1.1.1 summary enable
To disable summarization for the same area, enter the following:
-> ip ospf area 1.1.1.1 summary disable
Note. By default, an area has summarization enabled. Disabling summarization for an area is useful when
ranges need to be deactivated, but not deleted.
Displaying Area Status
You can check the status of the newly created area by using the show command, as demonstrated:
-> show ip ospf area 1.1.1.1
or
-> show ip ospf area
The first example gives specifics about area 1.1.1.1, and the second example shows all areas configured on
the router.
To display a stub area's parameters, use the
-> show ip ospf area 1.1.1.1 stub
Deleting an Area
To delete an area, enter the ip ospf area command as shown:
-> no ip ospf area 1.1.1.1
