Configuring OSPFv3
Assigning an area cost for OSPFv3 (optional parameter)
You can assign a cost for an area, but it is not required. To consolidate and summarize routes at an
area boundary, use the area range cost command in router configuration mode.
If the cost parameter is specified, it will be used (overriding the computed cost) to generate the
summary LSA. If the cost parameter is not specified, then the existing range metric computation
max or min cost of routes falling under this range will be used to generate summary LSA.
NOTE
The area should be already configured before using this command.
Example
Creates an area range entry with prefix 2001:db8::1/64 with the area-id 10.
Brocade(config)# ipv6 router ospf
Brocade(config-ospf6-router)# area 10 range 2001:db8::1/64
Modifies the address range status to DoNotAdvertise. Neither the individual intra-area routes
falling under range nor the ranged prefix is advertised as summary LSA.
Brocade(config)# ipv6 router ospf
Brocade(config-ospf6-router)# area 10 range 2001:db8::1/64 not-advertise
Modifies the address range status to advertise and a Type 3 summary link-state advertisement
(LSA) can be generated for this address range.
Brocade(config)# ipv6 router ospf
Brocade(config-ospf6-router)# area 10 range 2001:db8::1/64 advertise
Modifies the address range status to advertise and assign cost for this area range to 10.
Brocade(config)# ipv6 router ospf
Brocade(config-ospf6-router) # area 10 range 2001:db8::1/64 advertise cost 10
Modifies the address range status to not-advertise and cost from 10 to 5.
Brocade(config)# ipv6 router ospf
Brocade(config-ospf6-router)# area 10 range 2001:db8::1/64 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.
Brocade(config)# ipv6 router ospf
Brocade(config-ospf6-router)# no area 10 range 2001:db8::1/64 cost 5
Removes the area range.
Brocade(config)# ipv6 router ospf
Brocade(config-ospf6-router)# no area 10 range 2001:db8::1/64
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.
