Configuring Ospf Area Ranges - Avaya ERS 8800 series Configuration Manual

Configuring OSPF area ranges

Configure an area address range on the OSPF router to reduce the number of ABR
advertisements into other OSPF areas. An area address range is an implied contiguous range
of area network addresses for which the ABR advertises a single summary route.
You can use any value for the OSPF area name (for example, 1.1.1.1 or 200.200.200.200).
Procedure steps
Configure an OSPF area range by using the following command:
config ipv6 ospf area <ipaddr> range <ipv6addr-prefix>
Variable definitions
Use the data in the following table to use the config ipv6 ospf area range command.
advertise-metric <cost> lsa-type
<value>
advertise-mode <advertise|no-
advertise>
delete lsa-type <value>
create advertise-mode <value> lsa-
type <value> [advertise-metric
