Do you mean advertisizing those routes in Eigrp?

Eg

Router eigrp 100

Net 10.10.10.1 0.0.0.0

Net 10.10.11.1 0.0.0.0

Net 10.10.12.1 0.0.0.0

Int e0/0

Summary eigrp 10.10.0.0 0.0.255.255

When ever you need to generate a summary route, those routes need to be

advertised in the specific routing protocol before a summary is

generated.
