[j-nsp] BFD for EBGP on Juniper SRX650

[biwa net]

Hi

I am struggling to get a BFD session coming up over eBGP on Juniper SRX650
(junos 11.4)

I have set up the SRX650 in packet mode  , but for the life of me i am
unable to get the session up

The BGP BFD configuration is fine, as checked with documentation
(bfd-liveness-detection minimum-interval 1000 multiplier 3)

I am wondering if I need to configure host-inbound-service and allowing bfd
, I have tried but no success\

anyone had similar issues ?
