Configuring OSPFv3

• set tag <tag-value>
You must configure the route map before you configure a redistribution filter that uses the route
map.
When you use a route map for route redistribution, the software disregards the permit or deny action
of the route map.
For an external route that is redistributed into OSPFv3 through a route map, the metric value of the
route remains the same unless the metric is set by a set metric command inside the route map or
the default-metric <num> command. For a route redistributed without using a route map, the metric
is set by the metric parameter if set or the default-metric <num> command if the metric parameter
is not set.
Modifying default metric for routes redistributed into OSPF version 3
The default metric is a global parameter that specifies the cost applied by default to routes
redistributed into OSPFv3. The default value is 0.
If the metric parameter for the redistribute command is not set and the default-metric command is
set to 0, its default value, then routes redistributed from the various routing protocols will have the
metric value of the protocol from which they are redistributed. For information about the
redistribute command, refer to “Configuring route redistribution into OSPFv3” on page 1216.
You also can define the cost on individual interfaces. The interface cost overrides the default cost.
For information about defining the cost on individual interfaces, refer to “Modifying OSPFv3
interface defaults” on page 1226 and “Changing the reference bandwidth for the cost on OSPFv3
interfaces” on page 1215.
To assign a default metric of 4 to all routes imported into OSPFv3, enter the following command.
BigIron RX(config-ospf6-router)# default-metric 4
Syntax: [no] default-metric <number>
You can specify a value from 0 – 65535. The default is 0.
To restore the default metric to the default value, use the no form of this command.
Modifying metric type for routes redistributed into OSPF version 3
The Brocade device uses the metric-type parameter by default for all routes redistributed into
OSPFv3 unless you specify a different metric type for individual routes using the redistribute
command. (For more information about using the redistribute command, refer to “Redistributing
routes into OSPFv3” on page 1216).
A type 1 route specifies a small metric (two bytes), while a type 2 route specifies a big metric (three
bytes). The default value is type 2.
To modify the default value of type 2 to type 1, enter the following command.
