Abstract: Techniques are provided to manage how router advertisement messages are forwarded for ultimate wireless transmission in a wireless network. In one embodiment, a multicast router advertisement message intended for a virtual local area network is converted into individual unicast router advertisement messages directed to specific wireless mobile client devices that are part of that virtual local area network. In another embodiment, router advertisement messages are routed between controllers according to the current location of a wireless mobile client device. In still other embodiments, techniques are provided to minimize the volume of the router advertisement messages sent over a wireless network, and to proactively send a unicast router advertisement message to a mobile client device that has performed a handoff, without waiting for a router solicitation message.

Abstract translation: 提供技术来管理路由器通告消息如何被转发以用于无线网络中的最终无线传输。 在一个实施例中，旨在用于虚拟局域网的多播路由器通告消息被转换成针对作为该虚拟局域网的一部分的特定无线移动客户端设备的单独的单播路由器通告消息。 在另一实施例中，路由器通告消息根据无线移动客户端设备的当前位置在控制器之间路由。 在其他实施例中，提供了技术来最小化通过无线网络发送的路由器通告消息的音量，并且主动地向执行切换的移动客户端设备发送单播路由器通告消息，而不等待路由器请求消息 。
