BGP "no synchronization"

Hello guys,

how can I do the networks of ad networks that do not have static routes or are not connected?

The quagga / zebra, cisco or mikrotik have the synchronization.
I not found in the documentation “in synchronization” for BGP.

What better way to do this. Blackhole?
I made blackhole but not reach the ips addresses that are behind the block. I have an old version of vyatta where this works (Vyatta Core 6.1 2010.08.2).

I appreciate the help!

Maybe this method is good ?
