Configuring Ospf Areas - Avaya ERS 8800 series Configuration Manual

IPv6 routing configuration using the ACLI

Configuring OSPF areas

OSPF supports hierarchical routing by dividing the Autonomous System into different areas.
When two or more areas exist, the backbone area (area 0.0.0.0) must always be present.
You can use any value for the OSPF area name (for example, 1.1.1.1 or 200.200.200.200).
Prerequisites
You must log on to the OSPF Router Configuration mode in the ACLI.
Procedure steps

ipv6 area <A.B.C.D> default-cost <cost> import <value> [import-
