Hello,
Looks like Your return packets are not making it back to Your SRX. I see You are trying to advertise 1.1.1.0/24 out:
set policy-options policy-statement EBGP-output term out-networks from route-filter 1.1.1.0/24 exact
Question : do You have this exact route in the table vrflite.inet.0?
Please post the printouts:
show route table vrflite extensive | no-more show route advertising-protocol bgp 1.1.1.1 extensive | no-more
HTH
Thx
Alex
