To restore the default metric to the default value, use the no form of this command.
Modifying metric type for routes redistributed into OSPFv3
The 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.
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.
device(config-ospf6-router)# metric-type type1
Syntax: [no] metric-type {type1 | type2}
To restore the metric type to the default value, use the no form of this command.
Configuring external route summarization
When the Brocade device is an OSPF Autonomous System Boundary Router (ASBR), you can
configure it to advertise one external route as an aggregate for all redistributed routes that are covered
by a specified IPv6 address range.
When you configure an address range, the range takes effect immediately. All the imported routes are
summarized according to the configured address range. Imported routes that have already been
advertised and that fall within the range are flushed out of the AS and a single route corresponding to
the range is advertised.
If a route that falls within a configured address range is imported by the device, no action is taken if the
device has already advertised the aggregate route; otherwise, the device advertises the aggregate
route. If an imported route that falls within a configured address range is removed by the device, no
action is taken if there are other imported routes that fall with in the same address range; otherwise the
aggregate route is flushed.
You can configure up to 32 address ranges. The device sets the forwarding address of the aggregate
route to zero and sets the tag to zero.
If you delete an address range, the advertised aggregate route is flushed and all imported routes that
fall within the range are advertised individually.
If an external link state database overflow (LSDB) condition occurs, all aggregate routes are flushed out
of the AS, along with other external routes. When the device exits the external LSDB overflow condition,
all the imported routes are summarized according to the configured address ranges.
NOTE
If you use redistribution filters in addition to address ranges, the Brocade device applies the
redistribution filters to routes first, then applies them to the address ranges.
NOTE
If you disable redistribution, all the aggregate routes are flushed, along with other imported routes.
NOTE
This option affects only imported, type 5 external routes. A single type 5 LSA is generated and flooded
throughout the AS for multiple external routes.
