ROS7, announce single address

How do I announce one single /32 prefix over BGP? After upgrading from 6.48.1 to 7.1b4 connection has converted properly, it gets established, but:

/routing bgp network add network=10.100.10.41/32 synchronize=no

did not.

Is there any recent documentation somewhere? Rules from examples I found over the net doesn’t seem to be working.

With output networks in a bgp template. The example is here:

Thank you for the link; I’ve seen it earlier though. Turns out problem laid with badly converted (actually not converted at all) input filter that I missed. After removing it, things started to work. Do you know how the new “rule=” thing works?
