nv set vrf <vrf-id> router bgp peer-group <peer-group-id> address-family ipv6-unicast conditional-advertise enable

Turns BGP conditional advertisement on or off for IPv6 for the peer group. The default setting is off.

BGP conditional advertisement lets you advertise certain routes only if other routes either do or do not exist. BGP conditional advertisement is typically used in multihomed networks where BGP advertises some prefixes to one of the providers only if information from the other provider is not present. For example, a multihomed router can use conditional advertisement to choose which upstream provider learns about the routes it provides so that it can influence which provider handles traffic destined for the downstream router. This is useful for cost of service, latency, or other policy requirements that are not natively accounted for in BGP.
