Brocade Communications Systems FastIron X Series User Manual

NOTE
The ABR (device) will not inject the default route into an NSSA by default and the command described in this section will not
cause the device to inject the default route into the NSSA. To inject the default route into an NSSA, use the area nssa default-
information-originate command.
To enable default route origination, enter the following command.
device(config-ospf-router)# default-information-originate
-ospf-router)# default-information-originate
To disable the feature, enter the following command.
device(config
-ospf-router)# no default-information-originate
Syntax: [no] default-information-originate [ always ] [ metric value ] [ metric-type type ]
The always parameter advertises the default route regardless of whether or not the router has a default route. This option is disabled by
default.
NOTE
The always parameter is not necessary pre-FastIron 8.0 releases.
The metric value parameter species a metric for the default route. If this option is not used, the default metric is used for the route.
The metric-type type parameter species the external link type associated with the default route advertised into the OSPF routing
domain. The type can be one of the following:
• type1 - Type 1 external route
• type2 - Type 2 external route
If you do not use this option, the default redistribution metric type is used for the route type.
The route-map parameter overrides other options. If set commands for metric and metric-type are specied in the route-map, the
command-line values of metric and metric-type if specied, are “ignored” for clarication.
The route-map rmap parameter species the route map reference.
The corresponding route-map should be created before conguring the route-map option along with the default-information-originate
command . If the corresponding route-map was not been created beforehand, then the an error message will be displayed stating that
the route-map must be created.
NOTE
The route-map option cannot be used with a non-default address in the match conditions. The default-route LSA shall not be
generated if a default route is not present in the routing table and a match ip address condition for an existing non-default route
is congured in the route-map. The match ip-address command in the route-map is a no-op operation for the default
information originate command.
Supported match and set conditions
The supported match and set conditions of a normal route-map
conguration are as follows:
Match Conditions
ip nexthop prex-list prexList
ip nexthop accessList
