I'm not disagreeing with that at all ... just seemed implied somewhere that this could have operational impact and I was questioning why/how? As the private intercommunication within a Juniper box is in a private table, I don't believe it should be viewed as "public vs private" as that IP addressing can never been reached publicly anyways .... but as it does belong to a "routing table" I can see a strong need to follow standards based IP assignments instead of arbitrarily picking an IP range ....

But those routes are in "private tables"... does this really mean that Juniper is going to block the traffic when it doesn't seen it in inet.0 ? If it does actually block it (meaning someone has proven this out) then that's kinda scary... Apologies if I missed something earlier in a thread and my questions were already answered...;) Paul -----Original Message----- From: juniper-nsp-bounces [at] puck [mailto:juniper-nsp-bounces [at] puck] On Behalf Of Tarique A.
