Parameter

Parameter Description
Always
(Optional) Generate the default route
unconditionally, no matter whether the default
route exists locally or not.
metric metric
(Optional) Initial metric value of the default route,
1 by default
metric-type type
(Optional) Type of the default route. There are
two type of OSPF external routes: type 1,
different metrics seen on different devices; type
2, the same metric seens on different devices.
External route of type 1 is more trustworthy than
that of type 2. By default, it is type 2.
route-map
map-name
Associated route map name, no associated route
map by default
Default N/A.
Command
mode Routing process configuration mode.
Usage
guidelines
When the redistribute or default-information command is
executed, the OSPF-enabled device automatically turns into the
autonomous system border device (ASBR). But the ASBR cannot
generate default route automatically or advertise it to all the devices
in the OSPF routing domain. The ASBR generates default routes by
default. It is required to configure with the default-information
originate routing process configuration command.
If the always parameter is used, the OSPF routing process
advertises an external default route to the neighbors, no matter
whether the default route exists or not. However, the local device
does not show the default route. To make sure whether the default
route is generated, execute show ip ospf database to observe the
OSPF link state database. The external link identified with 0.0.0.0
indicates the default route. The execution of the show ip route
command on the OSPF neighbor will display the default route.
The metric of the external default route can be defined only with the
default-information originate command instead of the
default-metric command.
There are two types of OSPF external routes: type 1 external routes
