Figure 13-10. Advertising Area Summaries
You enable an ABR to send the summary for an area by specifying the range
of addresses in that area. From the OSPF configuration mode context, enter:
Syntax: area <area ID> range <network A.B.C.D> <subnet mask> [advertise | not-
advertise]
You can also specify whether or not the ABR should advertise the summary.
If you do not include an option for advertising, the router will automatically
advertise the summary. See "Prohibiting the Advertisement of Networks" on
page 13-51 for more details about using the not-advertise option.
For example, if area 1 included a single 24-bit subnet that the ABR should
advertise to other areas, you should enter:
ProCurve(config-ospf)# area 1 range 192.168.1.0 255.255.255.0 advertise
