Brocade Communications Systems FastIron SX Series User Manual

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 congured 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 species the IP address portion of the range. The software compares the address with the signicant 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 species 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 prex is advertised as summary LSA.
The cost cost-value parameter species the cost-value to be used while generating type-3 summary LSA. If the cost value is congured,
then congured cost is used while generating the summary LSA. If the cost value is not congured, 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 dene OSPF areas, you can assign interfaces to the areas. All router ports must be assigned to one of the dened 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.
To assign interface 1/1/8 of Router A to area 10.5.0.0 and then save the changes, enter the following commands.
RouterA(config)# interface ethernet 1/1/8
RouterA(config-if-e10000-1/1/8)# ip ospf area 10.5.0.0
RouterA(config-if-e10000-1/1/8)# write memory
Setting all OSPFv2 interfaces to the passive state
You can set all the Open Shortest Path First Version 2 (OSPFv2) interfaces to the default passive state using the default-passive-
interface command. When you
congure the interfaces as passive, the interfaces drop all the OSPFv2 control packets.
To set all the OSPFv2 interfaces to passive, enter the following command.
device# configure terminal
device(config)# router ospf vrf A
device(config-ospf-router-vrf-A)# default-passive-interface
Syntax: [no] default-passive-interface
