摘要： Link identifiers such as VIDs, selected from a defined range of values, are locally assigned by each node on a link state protocol controlled Ethernet network to each of its links or adjacencies. The link identifiers are assigned by the nodes such that each link or adjacency at the node is uniquely identified by a different link identifier. A link state protocol adjacency notification mechanism or other flooding mechanism is used to disseminate the locally assigned link identifiers to other nodes on the link state protocol controlled Ethernet network. The link identifiers are added by the nodes to their topology databases to enable detour routes to be locally calculated by the nodes on the network in a distributed manner. Upon occurrence of a failure, the link identifiers are used to source route traffic around the failure so that traffic may continue to traverse the link state protocol controlled Ethernet network.
摘要翻译：从定义的值范围中选择的诸如VID的链路标识符由链路状态协议控制的以太网上的每个节点本地分配给其每个链路或邻接。链路标识符由节点分配，使得节点处的每个链路或邻接被不同的链路标识符唯一地标识。链路状态协议邻接通知机制或其他洪泛机制用于将本地分配的链路标识符传播到链路状态协议控制的以太网上的其他节点。链路标识符被节点添加到它们的拓扑数据库中，以使得绕线路由由网络上的节点以分布式的方式在本地计算。发生故障时，链路标识符用于引发故障周围的路由流量，以便流量可以继续遍历链路状态协议控制的以太网。
