Though to answer your question :) Summarization means advertising the biggest network you choose/should advertise. If you had a /23 that was routed as 2 /24s in your network, you'd summarize those as a /23 on the way out of your network to keep the routing table smaller...
You should probably do the same for your next /24 unless you can find a specific reason not to. It saves headaches with route dampening in the long run if nothing else :) -----Original Message----- From: Anil Gupte [mailto:[EMAIL PROTECTED] Sent: Friday, 4 April 2003 7:21 AM To: [EMAIL PROTECTED] Subject: Re: IP route to Null0?
