area range

Use this command to define the range of IPv6 addresses to be used by Area Border Routers (ABRs) when they communicate routes to other areas.

Syntax

area area-id range ipv6-address [not-advertise]
no area area-id range ipv6-address [not-advertise]

Parameters

area-id Specifies the area at the boundary of which routes are to be summarized. Valid values are decimal values 0 - 4294967295 or dotted-quad notation.
ipv6-address Specifies IPv6 address and mask of routes to be summarized at the boundary of the specified area. Used only by ABRs.
not-advertise (Optional) Prevents advertisement of the specified IPv6 address range

Defaults

If not-advertise is not specified, the specified IPv6 address range is advertised.

Mode

OSPFv3 router configuration.

Usage

The “no” form of this command stops the routes from being summarized.

Example

This example shows how to define the address range as 2001:FA04:0005:0050::0/64 for summarized routes communicated at the boundary of area 0.0.0.0:

System(rw-config)->ipv6 router ospf 1
System(rw-config-ospfv3)->area 0.0.0.0 range 2001:FA04:0005:0050::0/64
