Hi Imran, You need at least one of the contributing routes to be present for the summary to work.
From: http://www.cisco.com/en/US/docs/ios/12_0t/12_0t7/feature/guide/sumadr.html RIPv2 route summarization requires that the lowest metric of the "best route" of an aggregated entry, or the lowest metric of all current child routes, be advertised. The best metric for aggregated summarized routes is calculated at route initialization or when there are metric modifications of specific routes at advertisement time, and not at the time the aggregated routes are advertised.
