Can you elaborate on that? Will the RE-2000 not work with JunOS 15+? We 
are actually planning to upgrade to JunOS soon because it supports NDP 
cache protection:

I know it's quite now and not recommended but in my eyes this feature is 
quite important to secure the network unless you want to assign /126 and 
alike  to your customers instead of the recommended, typical /64 and 
increase management overhead for everybody involved.


Thanks,
Jeff
