    • A method and apparatus for the dissemination of non-routing information to nodes of a network is provided. A new type of IS-IS packet (called a NRI IS-IS packet) is described that exclusively carries non-routing information. When the NRI IS-IS packet is received by a router, the router may send the NRI IS-IS packet to an appropriate component responsible for processing non-routing information, without analyzing, verifying, and validating the information carried in each TLV and sub-TLV of the NRI IS-IS packet. Advantageously, the time it takes for routers of the network to achieve convergence is decreased since a IS-IS packet reader need not analyze, verify, and validate information not related to network topology and IP routing. Therefore, when NRI IS-IS packets are received, there is no impact in the convergence time of nodes in the network.
    • 提供了一种用于将非路由信息传播到网络节点的方法和装置。 描述了一种新型的IS-IS分组(称为NRI IS-IS分组),其独有地携带非路由信息。 当路由器接收到NRI IS-IS报文时,路由器可以将NRI IS-IS报文发送给负责处理非路由信息的适当组件,而无需分析,验证和验证每个TLV和Sub -TLV的NRI IS-IS包。 有利的是,由于IS-IS分组读取器不需要分析,验证和验证与网络拓扑和IP路由不相关的信息,所以网络路由器实现收敛所需的时间被减少。 因此,当收到NRI IS-IS报文时,网络节点的收敛时间不会有任何影响。
