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. Therefore, each area needs to be structured 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 an address range can be summarized on any bit
boundary in a network address.
• To summarize the external LSAs imported into the autonomous system
(that is, local routing domain), use the Summary Address Configuration
screen (page 458).
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.
