Hello,

On my mx240 ( 11.4R5.5) i try to make virtual router with additional bgp 
session to my isp. Main bgp session in main routing table goes via 
ae0.74, extra session in vr blackhole should go via ae0.77. Problem is 
that there is no communication with peer in this virtual router. When i 
ping remote site from interface in vr blackhole i see this packets on 
interface in main router.. I don't know why junos  transmit packets via 
main routing table ?

Appreciate the help
many thanks
Peter
