摘要： The invention is directed to providing NDP mediation over an IP interworking VLL. ICMPv6 Neighbor Discovery and Inverse Neighbor Discovery messages are intercepted by provider edge (PE) devices to learn both IPv6 interface addresses and link-layer addresses of customer edge (CE) devices before forwarding the messages to the CE devices, and in some cases after altering the messages to make them more meaningful to the receiving CE devices. In this manner, the CE device interface addresses do not need to be communicated over the LDP control link, as in IPv4 ARP Mediation.
摘要翻译：本发明旨在通过IP互通VLL提供NDP中介。 ICMPv6邻居发现和反向邻居发现消息由提供商边缘（PE）设备拦截，以在将消息转发到CE设备之前学习客户边缘（CE）设备的IPv6接口地址和链路层地址，并且在某些情况下改变消息使其对接收CE设备更有意义。以这种方式，CE设备接口地址不需要通过LDP控制链路进行通信，如IPv4 ARP中介。

摘要： A method and apparatus for communicating and utilizing link connection type characteristics in a communications network begins by determining the connection type characteristics for a link within the network. The connection type characteristics preferably include the partitioning of the available bandwidth of the link. The connection type characteristics for the link are advertised to at least one node in the network. The connection type characteristics are then used to perform network functions such as selecting routing paths for new connections. When a change occurs in the link that results in altered connection type characteristics for the link, the altered connection type characteristics are determined and advertised in a similar manner.
