45.3.3.6 Configuring Routing Summary in the OSPF Area
The feature enables the ABR to broadcast a summary route to other areas. In OSPF, ABR is to broadcast
every network to other areas. If the network number is distributed serially according to some method, you can
configure ABR to broadcast a summary route to other areas. The summary route can cover all networks in a
certain range.
Run the following command in switch configuration mode to set the address range:
Command Purpose
areaarea-idrangeaddress mask
Sets the address range of the summary
area.
45.3.3.7 Configuring Forwarded Routing Summary
When the routes are distributed from other areas to the OSPF area, each route will be uniquely broadcast in
the exterior LSA method. However, you can configure the switch to broadcast a route, which can cover a
certain address area. This method reduces the size of the OSPF link state database.
Run the following command in switch configuration mode to configure the summary route:
Command Purpose
summary-addressprefixmask [not
advertise]
Describes the address and mask
covering the distributed route. Only one
summary route is broadcast.
45.3.3.8 Generating Default Route
ASBR requires generating a default route to enter the OSPF route area. When you configure the switch to
distribute the route to the OSPF area, the route automatically becomes ASBR. However, default ASBR does
not generate the default route to enter the OSPF routing area.
Run the following command in switch configuration mode to force ASBR to generate the default route.
Command Purpose
default-information originate [always]
[route-map map-name]
Forces ASBR to generate the default
route.
