Hi,
Assume that two prefix are advertised by router to hosts in the network. After some time the administrator deletes one of the prefixes and the future router advertisement will carry only one prefix.

What will hosts do with  the deleted prefix? 
Whether the addresses will be deleted after some time? What is this time?

From the specs i found that the addresses are deleted only if the router advertises prefix with valid life time of zero. Whether the rtadvd daemon has to send any such message with deleted prefix life time set to zero?

I feel that the addresses should be deleted immediately if a router stops advertising the prefix.

regards
ravi prasad.
