From Screenos 5.3 or later, the BGP soft reset options are supported.
Soft-in option:
clear vrouter trust-vr protocol bgp neighbor ip_addr soft-in
This enables a soft reset and generates an inbound update from a BGP neighbor. A soft reset allows the application of a new or changed policy, without clearing an active BGP session. The route-refresh feature occurs on a per-neighbor basis and does not require preconfiguration or extra memory.
Soft-out option:
clear vrouter trust-vr protocol bgp neighbor ip_addr soft-out
This enables a soft reset and sends a new set of updates to a BGP neighbor. A soft reset allows the application of a new or changed policy, without clearing an active BGP session. The route-refresh feature occurs on a per-neighbor basis and outbound resets do not require pre configuration or routing table update storage.
