Configuring OSPF route control
This section describes how to control the advertisement and reception of OSPF routing information, as
well as route redistribution from other protocols.
Configuration prerequisites
Before configuring OSPF route control, complete the following tasks:
• Configure IP addresses for interfaces
• Configure OSPF basic functions
• Configure filters if routing information filtering is needed
Configuring OSPF route summarization
Route summarization is when an ABR or ASBR summarizes routes with the same prefix into a single route
and distributes it to other areas.
Route summarization reduces the traffic of routing information exchanged between areas and the sizes
of routing tables on routers, improving route calculation speed on routers.
For example, there are three internal routes in an area: 19.1.1.0/24, 19.1.2.0/24, and 19.1.3.0/24. By
configuring route summarization on the ABR, the three routes are summarized into the route 19.1.0.0/16
that is advertised to other areas.
