[j-nsp] JUNOS and 128.0.0.0 martian (JFYI)

[Paul Stewart]

Pardon me for asking this...

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

So with 128/16 going live, Juniper may also additionally need to change
their internal addressing!
