Route summarization is the consolidation of advertised addresses. This feature causes a single summary route to be advertised to other areas by an ABR. In OSPF, an ABR will advertise networks in one area into another area. If the network numbers in an area are assigned in a way such that they are contiguous, you can configure the ABR to advertise a summary route that covers all the individual networks within the area that fall into the specified range.
There we will not show configuration procedure for all components are needed for OSPF (IP ports, OSPF port, neighbors, etc.) You can see it in any previous example.

Stub areas are areas into which information on external routes is not sent. Instead, there is a default external route generated by the area border router, into the stub area for the destination outside the autonomous system. The cost of a default route depends on the value of DEFCOST filed.
There we will not show configuration procedure for all components are needed for OSPF (IP ports, OSPF resource, neighbors, etc.) You can see it in any previous example.

The normal situation is when we have used more as one routing protocols in our networks. It can be static routing, RIP, OSPF or any other IGP protocol.
For correct work such networks we must have the possibility to redistribute routes from one routing protocol to any other. It means that routes were detected through RIP or static protocols must be known in OSPF Autonomous System and routes were detected through OSPF protocol must be known on all routes that use RIP protocol.
CPX allow to redistribute OSPF routes into common routes' table and redistribute local, static, RIP routes from common routes' table to OSPF AS.
Configure and activate OSPF resource.
Select types of route that we want to redistribute into OSPF. If need you can set a separate cost (metric) for each type of routes. In another case will be used default metric.
