Identification and removal of failed server is responsibility of administrator. Then the bridge fails, partitioning the network. Client Y will attempt to renew several times, and fail since it can't talk to server A. Eventually, client Y will broadcast a rebinding which server B will receive. When it fails to get an answer, server B will renew client Y's lease on its IP address. This works because an IP address cannot change the client to which it is bound without the entire server group's awareness.
Servers verify basic configuration information.
