A number of these prefixes were used in early documentation and as such were widely deployed by early adopters of IP. In the "bad old days" a large number of sites stood up IP networks in isolation, only interconecting -after- inital rollout was done. Consider it as an early empirical trials with RFC 1918 space :) Based on the confusion, 192.0.2.0/24 was earmarked for use in documentation... :) I know of no good reason why Juniper continues to flag these legacy blocks. --bill
