Configuring Area Ranges (Route Summarization for ABRs)

An OSPF area can include a large number of nodes.

networks within its area. When using route

summaries, local changes do not have to be propagated to other area routers. This allows OSPF to be easily scaled for larger networks, and provides a more stable network topology.

Command Usage

Use the Area Range Configuration page to summarize the routes for an area. The summary route for an area is defined by an IP address and network mask. You therefore need to structure each area with a contiguous set of addresses so that all routes in the area fall within an easily specified range. This router also supports Variable Length Subnet Masks (VLSMs), so you can summarize an address range on any bit boundary in a network address.

To summarize the external LSAs imported into your autonomous system (i.e., local routing domain), use the Summary Address Configuration screen (page 3-252).

Command Attributes

Area ID – Identifies an area for which the routes are summarized. (The area ID must be in the form of an IP address.)

Range Network – Base address for the routes to summarize.

Range Netmask – Network mask for the summary route.

Advertising – Indicates whether or not to advertise the summary route. If the summary is not sent, the routes remain hidden from the rest of the network. (Default: Advertise)

Note: This router supports up 64 summary routes for area ranges.
