Configuring Default Route Origination - Dell PowerConnect B-RX Configuration Manual

After this distribution list is configured, the internal routes would be included, and the external
routes would be omitted from the OSPFv3 route table.

Configuring default route origination

When the Brocade device is an OSPF Autonomous System Boundary Router (ASBR), you can
configure it to automatically generate a default external route into an OSPFv3 routing domain. This
feature is called "default route origination" or "default information origination."
By default, the Brocade device does not advertise the default route into the OSPFv3 domain. If you
want the device to advertise the OSPF default route, you must explicitly enable default route
origination.
When you enable OSPF default route origination, the device advertises a type 5 default route that is
flooded throughout the AS (except stub areas).
The device advertises the default route into OSPF even if OSPF route redistribution is not enabled,
and even if the default route is learned through an IBGP neighbor.
NOTE
The Brocade device does not advertise the OSPF default route, regardless of other configuration
parameters, unless you explicitly enable default route origination.
If default route origination is enabled and you disable it, the default route originated by the device
is flushed. Default routes generated by other OSPF routers are not affected. If you re-enable the
feature, the feature takes effect immediately and thus does not require you to reload the software.
For example, to create and advertise a default route with a metric of 2 and as a type 1 external
route, enter the following command.
BigIron RX(config-ospf6-router)# default-information-originate always metric 2
metric-type type1
Syntax: [no] default-information-originate [always] [metric <value>] [metric-type <type>]
The always keyword originates a default route regardless of whether the device has learned a
default route. This option is disabled by default.
The metric <value> parameter specifies a metric for the default route. If this option is not used, the
value of the default-metric command is used for the route. For information about this command,
refer to
