[j-nsp] M-series IPSEC / SP interface and VRF

So, if I understand Your requirement, You want sp-0/0/0.<unit> in VRF, 
correct?
And outgoing GE interface in inet.0?
And where the decrypted packets should be placed, inet.0 or VRF?
And where from the to-be-ecrypted packets should arrive, from inet.0 or VRF?
If the answer is "correct/inet.0/VRF/VRF" then migrate to next-hop-style 
IPSec and place inside sp-* unit into the VRF leaving outside sp-* unit 
in inet.0.
HTH
Thanks
Alex
