Modifies the address range status to advertise and a Type 3 summary link-state advertisement (LSA)
can be generated for this address range.
device(config)# router ospf
device(config-ospf-router)#area 10 range 10.1.1.1 255.255.255.0 advertise
Modifies the address range status to advertise and assign cost for this area range to 10.
device(config)# router ospf
device(config-ospf-router)#area 10 range 10.1.1.1 255.255.255.0 advertise cost 10
Modifies the address range status to not-advertise and cost from 10 to 5.
device(config)# router ospf
device(config-ospf-router)# area 10 range 10.1.1.1 255.255.255.0 not-advertise cost 5
Removes the cost from the area range. The area range will be advertised with computed cost which is
the max/min(based on RFC 1583 compatibility) of all individual intra-area routes falling under this range.
device(config)# router ospf
device(config-ospf-router)# no area 10 range 10.1.1.1 255.255.255.0 cost 5
Removes the area range.
device(config)# router ospf
device(config-ospf-router)# no area 10 range 10.1.1.1 255.255.255.0
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 | ip-addr range ip-addr ip-mask [ advertise | not-advertise ] cost cost-value }
The num and ip-addr parameters specify the area number, which can be in IP address format.
The range ip-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 ip-mask parameter specifies the portions of the IP address that a route must contain to be
summarized in the summary 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 -
16777215.
To disable this function, use the no form of this command.
Assigning interfaces to an area
Once you define OSPF areas, you can assign interfaces to the areas. All router ports must be assigned
to one of the defined areas on an OSPF router. When a port is assigned to an area, all corresponding
subnets on that port are automatically included in the assignment.
