Question #1: Given the following block of IP prefixes, how many filtering statements (standard access-lists, extended access-lists or prefix-lists)are needed to permit these prefixes and only these prefixes:
Question #2: Given the following block of IP prefixes, how many filtering statements (standard access-lists, extended access-lists or prefix-lists)are needed to permit these prefixes and only these prefixes:
Please note the extreme similarities between the address blocks listed in both Question #1 and Question #2. This similarity generated many surprising results for many of the students in the NetMasterClass Llive On-line Group Mentoring Session. Please come back to view the answer on Friday, May 7th.
