Layer 3 Routing Commands
1634
type 3 summary LSA is not advertised, but contained networks are suppressed.
This behavior is equivalent to specifying the not-advertise option. If the range is
configured for type 7 to type 5 translation, a type 5 LSA is sent if the metric is set
to 16,777,215; however, other routers will not compute a route from a type 5
LSA with this metric.
Default Configuration
No area ranges are configured by default. No cost is configured by default.
Command Mode
OSPFv2 Router Configuration mode
User Guidelines
The no form of this command can be used to delete an area range. For
example:
!! Create area range
console (config-router)#area 1 range 10.0.0.0 255.0.0.0 summarylink
!! Delete area range
console (config-router)#no area 1 range 10.0.0.0 255.0.0.0 summarylink
The no form may be used to revert the [advertise | not-advertise] option to
its default without deleting the area range. Deleting and recreating the area
range would cause OSPF to temporarily advertise the prefixes contained
within the range. Note that using either the advertise or not-advertise
keyword reverts the configuration to the default. For example:
!! Create area range. Suppress summary.
console (config-router)#area 1 range 10.0.0.0 255.0.0.0 summarylink not-
advertise
!! Advertise summary.
console (config-router)#no area 1 range 10.0.0.0 255.0.0.0 summarylink not-
advertise
The no form may be use to remove a static area range cost, so that OSPF sets
the cost to the largest cost among the contained routes. For example:
!! Create area range with static cost.
console (config-router)#area 1 range 10.0.0.0 255.0.0.0 summarylink cost 1000
!! Remove static cost.
console (config-router)#no area 1 range 10.0.0.0 255.0.0.0 summarylink cost
