BFD forwarding是指在网络设备中启用BFD功能,以监测网络路径的有效性,并在检测到故障时快速切换路由或进行其他故障恢复操作。这有助于提高网络的可靠性和稳定性。 阐述remote-discriminator在bfd forwarding中的作用: Remote-discriminator在BFD forwarding中用于唯一标识对端的BFD会话。在多对BFD会话存在于同一网络路径上时...
undo bfd forwarding match remote-discriminator命令用来去使能匹配对端配置的BFD本地描述符。 缺省情况下,远端描述符未配置。 该命令仅在S5755-H,S6730-H-V2,S5732-H-V2产品上支持。 命令格式 bfd forwarding match remote-discriminator discriminator-value [ to discriminator-value ] undo bfd forwarding match...
bfd forwarding matchremote-discriminatordiscriminator-value[todiscriminator-value] 缺省情况下,未配置单臂BFD会话的远端标识符。 检查配置结果 执行命令display bfd session{all{ [for-ip] |for-ipv6} |discriminatordiscr-value|dynamic|peer-ip{peer-ip[vpn-instancevpn-instance-name] |default-ip} |peer-ipv6...
bfd forwarding match remote-discriminator discr-value-list { discr-value1 [ to discr-value2 ] } &<1-10> 缺省情况下,未配置本地的BFD会话远端标识符 1.7 开启告警功能 开启BFD模块的告警功能后,该模块会生成告警信息,用于报告该模块的重要事件。生成的告警信息将发送到设备的SNMP模块,通过设置SNMP中告警...
bfd forwarding match remote-discriminator discr-value-list { discr-value1 [ to discr-value2 ] } &<1-10> By default, no remote discriminators of static BFD sessions are specified for the local device. Enabling SNMP notifications for BFD About this task To report critical BFD events to an ...
Run display current-configuration configuration bfd to check whether the local and remote discriminators at both ends of the BFD session match. If local and remote discriminators at both ends match, go to 2. If the local and remote discriminators at both ends do not match, run discriminator...
RFC 5880Bidirectional Forwarding Detection June 2010Once the remote end echoes back the local discriminator, all further received packets are demultiplexed based on the Your Discriminator field only (which means that, among other things, the source address field can change or the interface over which...
LD/RD :: Local Discriminator/Remote Discriminator Holdown :: rx-interval*multiplier for the egress interface (mult) :: multiplier value for the egress interface Last Up :: Timestamp(in 100ths of a second since system up) from the last time the peer session came up ...
For example, the first BFD control packet may include a remote discriminator number associated with the remote end device and a local discriminator number presumed to be associated with the local end device. The method further includes a step of replying to the remote end device with a second ...
Seamless Bidirectional Forwarding Detection Release 24.2.1 This feature introduces support for NCS 5500 routers as a Seamless BFD (S-BFD) reflector. Seamless BFD simplifies the negotiation and state establishment aspects of BFD by predetermining session discriminators and maintaining session...
