Way to use Bird as route server

[Osmos]

Hi there,

     just doing some tests with Bird as route server, but the result was not the desired.
     Other staff like RTBH is running fine.
 
     The situation is that next-hop is not modified (used only RS CLIENT option).
     All are eBGP sessions. 

     Checked some examples around and found no way to deploy correctly.
     Any advise or template to achieve this function?

Thanks in advance.
Regards,
Jorge.
