Hi John Yes your superior is right. For instance.
Your NY site has 2 networks 10.64.8.0 10.64.9.0 8 = 0000 1000 in binary 9 = 0000 1001 in binary so you will match the first 16 bits for 10.64 and then you will match the next 7 bits 0000 100 16 + 7 = 23 10.64.8.0/23 will summarise those 2 networks, and so on.. Summarisation is nice to have, but if you have 2 networks at each site, I'm sure OSPF will do fine without the summarise network :) Cheers Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=49095&t=49085 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
