Ok, I removed export statement from "protocols bgp group TEST" and flow 
routes are
now advertised:

show route advertising-protocol bgp 192.168.2.2

inetflow.0: 2 destinations, 2 routes (2 active, 0 holddown, 0 hidden)
  Prefix                  Nexthop              MED     Lclpref    AS path
  *,10.10.10/24/40
*                         Self                                    I
  *,10.0.0.1/48
*                         Self                                    I

But as expected unicast prefixes are now not advertised.
The question is how I advertise unicast prefixes at the same time?

Regards
Dmitri
