New Features (continued)
Prefixes after maximum aggregation
Eliminate all subnets of prefixes appearing in routing table and originated by the same AS
e.g. 158.43.0.0/16 is announced from AS1849, all subnets which also are originated by AS1849 are dropped/ignored
Represents aggregation effort by the AS (but obviously can not account for traffic engineering)
Represents the smallest the Internet Routing table can be without losing any detailed reachability information
