摘要： In some embodiments, an apparatus comprises a core network node configured to be operatively coupled to a set of network nodes. The core network node is configured to receive a broadcast signal from a network node from the set of network nodes, which is originated from a host device operatively coupled to the network node. The broadcast signal is sent via a tunnel from the network node to the core network node, such that other network nodes that are not included in the tunnel do not receive the broadcast signal. The core network node is configured to retrieve control information associated with the broadcast signal without sending another broadcast signal, and then send the control information to the network node.

摘要： Techniques are provided to enable support of roaming wireless devices in a network such that the wireless devices can keep their Internet Protocol (IP) addresses as they roam across mobility sub-domains. Traffic for a wireless device that roams is tunneled back to the access switch that serves the IP subnet which includes an IP address for the wireless device. Traffic is tunneled back to that access switch for the wireless device when the wireless device roams to another access switch which does not serve the IP subnet for the wireless device in the same mobility sub-domain and when the wireless device roams to a different mobility sub-domain, in which case the traffic is tunneled between tunneling endpoints in the respective mobility sub-domains.

摘要： 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.
