[c-nsp] BFD on ASR 9000

[chams]

Hi,
 
I have to configure a bfd session between my ASR and a Firewall, over a BGP 
session.
but after configuration i ca't even see the configured session when doing a 
"show bfd session".
by  reading some cisco docs, i've seen that BFD can be configured onlu on  point 
to point eBGP session, my ASR and Firewall have an eBGP point to  point session 
but they belong to the same confederation (perhaps BFD see  it as iBGP session)
 
Thanks for Help.
