[j-nsp] 6VPE routes learned and hidden - ACX5048

So, you're trying to leak between local VRFs on the same ACX?  With prefix 
1234:5678:0:7::/64 originating in "three" and you want to leak locally into 
"one"?

I know local leaking isn't possible on e.g. EX4550, but I don't know if 
that same limitation applies to the ACX.  If you *are* able to leak locally 
between VRFs, you'll need auto-export in the VRF to make it work:
