I have the following addresses

and have created 2 summary addresses of /24 and so that i can redistribute them into an igrp process that is addressed with a 24bit mask.

The summary routes appear when I use show ip ospf summary-address, they do not appear in ospf routing table and are not redistributed into igrp.

Is this because the routes that make up the summary have a longer mask that the summary and therefore not entered into the ospf routing table

From the IOS 12.0 Network Protocols Command Reference, Part 1, OSPF section concering the

address-summary command:

"For OSPF, this command summarizes only routes from other routing protocols that are being

redistributed into OSPF."

Basically the summary-address command will not summarize OSPF routes. If possible, perhaps you can

create static routes to the and networks pointing to the null0 interface

and redistribute these static routes into IGRP. Note: if you have additional static routes configured,

you may need to use route maps to control what static routes get distributed into each routing
