NOTE
This command does not work in incremental fashion. So both the optional parameters have to be
configured each time. Otherwise it will take the default value.
Syntax: [no] area {num | ipv6-addr} range ipv6-addr/ipv6-subnet-mask [advertise | not-advertise]
[cost cost-value]
The num and ipv6-addr parameters specify the area number, which can be in IP address format.
The range ipv6-addr parameter specifies the IP address portion of the range. The software compares
the address with the significant bits in the mask. All network addresses that match this comparison are
summarized in a single route advertised by the router.
The ipv6-subnet-mask parameter specifies the portions of the IPv6 address that a route must contain to
be summarized in the summary route. In the example above, all networks that begin with 193.45 are
summarized into a single route.
The advertise parameter sets the address range status to advertise and generates a Type 3 summary
link-state advertisement (LSA). If at least a single route falls under the range, a ranged LSA will be
advertised.
The not-advertise parameter sets the address range status to DoNotAdvertise. Neither the individual
intra-area routes falling under range nor the ranged prefix is advertised as summary LSA.
The cost cost-value parameter specifies the cost-value to be used while generating type-3 summary
LSA. If the cost value is configured, then configured cost is used while generating the summary LSA. If
the cost value is not configured, then computed range cost will be used. The cost-value ranges from 1
to 16777215.
To disable this function, use the no form of this command.
Assigning interfaces to an area
After you define OSPFv3 areas, you must assign device interfaces to the areas. All device interfaces
must be assigned to one of the defined areas on an OSPF router. When an interface is assigned to an
area, all corresponding subnets on that interface are automatically included in the assignment.
For example, to assign Ethernet interface 3/1 to area 10.5.0.0, enter the following commands.
device(config)# interface Ethernet 3/1
device(config-if-e100-3/1)# ipv6 ospf area 10.5.0.0
Syntax: [no] ipv6 ospf area {number | ipv4-address}
The number and ipv4-address parameters specify the area number, which can be a number or in IPv4
address format. If you specify a number, the number can be from 0 through 2,147,483,647.
To remove the interface from the specified area, use the no form of this command.
Specifying a network type
You can specify a point-to-point or broadcast network type for any OSPF interface of the following
types: Ethernet, or VE interface. To specify the network type for an OSPF interface, use the following
commands.
device(config)# interface ethernet 3/1
device(config-if-e100-3/1)# ipv6 ospf network broadcast
Syntax: [no] ipv6 ospf network {point-to-point | broadcast}
