OSPF介绍 是一种内部网关协议(Interior Gateway Protocol,IGP),用于在单一自治系统(Autonomous System,AS)内决策路由。OSPF是一种基于链路状态(Link-state)的路由协议,它使用链路状态信息做出路由决策,使用最短路径优先(SPF)算法(也称为Dijkstra 算法)进行路由计算。 核心命令语法 代码语言:javascript 复制 [Huawei]bfd[...
通过ARP(Address Resolution Protocol)、ND(Neighbor Discovery Protocol)、LACP(Link Aggregation Control Protocol,链路聚合控制协议)或者BFD(Bidirectional Forwarding Detection,双向转发检测)来检测网络中是否存在多个IRF。 (2)冲突处理 IRF分裂后,通过分裂检测机制IRF会检测到网络中存在其它处于Active状态(表示IRF处于正常工...

In this case, applications use the Hello mechanism of the upper-layer protocol to detect faults, which takes usually seconds. This long detection period causes severe packet loss when traffic is transmitted at gigabit rates. On a Layer 3 network, the Hello mechanism cannot detect faults for all...
双向转发检测BFD(Bidirectional Forwarding Detection)主要用于检测转发引擎之间的通信故障。具体来说,BFD对两个系统间的、同一路径上的一种数据协议(data protocol)的连通性进行检测。这条路径可以是物理链路或逻辑链路,其中就包括TE隧道。 使用BFD检测整条TE隧道,可触发VPN FRR应用在主路径故障时进行快速流量切换,以减少...
