[j-nsp] how are routes leaked from MP-BGP table to a VRF

[adamv0025 at netconsultings.com]

Hi folks,

Would appreciate any clues regarding the mechanism behind installing routes
from MP-BGP table to a VRF table please? 
Is it triggered or periodic? 
Are routes in MP-BGP grouped based on common RTs and VRFs grouped based on
import-policy commonalities, to speed up the search through MP-BGP table
please? 
Currently experiencing 5-10min delay in installing routes form MP-BGP(~1.3M
active ~2.6 total) to a VRF(couple routes need to be leaked).
