4-5
type
: Default type of external routes redistributed by OSPF. The value of this argument is 1 or 2.
Description
Use the
default
command to configure the default parameters for redistributed routes, including cost,
interval, limit, tag, and type.
Use the
undo default cost
command to restore the default.
By default, the cost, interval, limit, tag, and type are 1, 1, 1000, 1, and 2, respectively.
When OSPF redistributes external routes and propagates them in the entire autonomous system
z
The cost of external routes can influence route selection and calculation.
z
The performance of the device will be degraded significantly if OSPF redistributes routes
frequently.
z
The performance will also be degraded significantly if OSPF redistributes a large number of routes
at one time.
Therefore, it is necessary to reasonably set the default cost of redistributed routes, the default interval
for redistributing routes, and the limit of routes that can be redistributed at one time.
Examples
# Set the default cost, interval, limit, tag, and type of redistributed routes to 10, 20 seconds, 300, 15,
and 1, respectively.

Parameters
value
: Cost of the default route, in the range of 0 to 16777214.
Description
Use the
default-cost
command to configure the cost of the default route advertised by OSPF to a Stub
area or NSSA.
Use the
undo default-cost
command to restore the default.
By default, the cost of the default route advertised by OSPF to a Stub area or NSSA is 1.
This command only applies to an ABR in a Stub area or NSSA.
To configure a Stub area, you need to use the
stub
and
default-cost
commands.
