6.11.11 Configuring Route Summarization When Redistributing Routes into OSPF

When routes from other protocols are redistributed into OSPF, each route is advertised individually in
an external LSA. However, you can configure the D-Link router to advertise a single route for all the
redistributed routes that are covered by a specified network address and mask. Doing so helps
decrease the size of the OSPF link-state database.
To configure route summarization, use the following command in router configuration mode:
summary-address prefix mask [not
advertise]
In the prompt Select 20 option ，then prompt is as below:
(00)A.B.C.D

6.11.12 Generate a Default Route

You can force an autonomous system boundary router to generate a default route into an OSPF routing
domain. Whenever you specifically configure redistribution of routes into an OSPF routing domain, the
router automatically becomes an autonomous system boundary router. However, an autonomous
system boundary router does not, by default, generate a default route into the OSPF routing domain.
To force the autonomous system boundary router to generate a default route, use the following
command in router configuration mode:
default-information
[always] [route-map map-name]
In the prompt Select 4 option ，prompt is as below:
IP address mask for match network
Command
IP summary address
Summary mask
Do not advertise when translating OSPF type-7 LSA
Command
originate
Model Name
Function
Specify an address and mask that covers redistributed
routes, so only one summary route is advertised.
Function
Force the autonomous system boundary router to
generate a default route into the OSPF routing domain.
