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 1/3/1 to area 10.5.0.0, enter the following commands.
device(config)# interface Ethernet 1/3/1
device(config-if-e100-1/3/1)# 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 1/3/1
device(config-if-e100-1/3/1)# ipv6 ospf network broadcast
Syntax: [no] ipv6 ospf network { point-to-point | broadcast }
The point-to-point parameter specifies that the OSPF interface will support point-to-point networking. This is the default setting for
tunnel interfaces.
The broadcast parameter specifies that the OSPF interface will support broadcast networking. This is the default setting for Ethernet and
VE interfaces.
The no form of the command disables the command configuration.
Configuring virtual links
All ABRs must have either a direct or indirect link to an OSPF backbone area (0.0.0.0 or 0). If an ABR does not have a physical link to a
backbone area, you can configure a virtual link from the ABR to another router within the same area that has a physical connection to the
backbone area.
