There are a few ways to do it, check below..
1. On RouterB assign a secondary address (on the same interface as
10.0.0.0/24) as 10.0.1.17/28 , and on RouterC assign a secondary address of
10.0.1.8/28.
Ur other /28 should now be seen in the route table.
2. The other way to do it is, create a loopback with 10.0.1.17/28.
Redistribute connected into ospf process. Then do a summary address
10.0.1.0/255 under ospf process, your route should be visible on the
RouterC.
There are a couple of other ways to do it. But the basic idea is the same.
You have to generate an equal mask as the mask on the interface if the major
network is the same. IF major network is different, it will summarise to
classful boundary.

> hi, Erhan
> assume there are three routers,RouterA has ospf area 0 and have a network
10.0.1.0/28, RouterB has ospf area 0,rip ,RouterC has rip. RouterB learn
route 10.0.1.0/28 from RouterA, and want redistribute it into
RouterC,RouterB and RouterC links by 10.0.0.0/24. static route is not
allowed,how to resove it?
