When summarization is configured on an interface the router immediately creates a route pointing to nullO. - Loop-prevention mechanism When the last specific route of the summary goes away the summary is deleted. The minimum metric of the specific routes is used as the metric of the summary route. 5CI 2008 Cis ms I All ng Học viện mạng Bách Khoa - www.bkacad.com 2 CCNP - BSCI Bachkhoa Networking Academy Summarizing EIGRP Routes no auto-summary EIGRP automatically summarizes routes at the classful boundary the boundary where the network address ends as defined by class-based addressing. 5CI 2008 Cisco Systems Inc.

In the presence of discontiguous subnetworks automatic summarization must be disabled for routing to work properly. To turn off auto-summarization use the following .
