bfd fast-detect bfd multiplier 3 bfd minimum-interval 500 解决方案 从华为设备上创建的BFD会话看,该会话是没有绑定接口的。说明该bfd for ip是多跳会话,多条会话ttl值默认为253; 而对端友商会话信息中没有体现出单多跳和ttl信息,一般友商BFD for ip会话ttl为255 ; ...
1、V200R002C50及之后版本,配置BFD与传输设备对接时,建议配置port-status fast-detect enable命令使能芯片快速感知接口物理状态变化功能,同时BFD检测间隔建议配置为500ms4、1000ms3或者更大值。 2、缺省情况下,BFD使用组播IP地址224.0.0.184。 BFD联动功能: 1、 配置BFD与接口状态联动:(该功能针对绑定出接口且使用缺...

bfd fast-detect ipv4#启用address-family ipv4的bfd检测功能 由于我们已经在路由器接口上启用了BFD检测,因此就不需要再调整ISIS的默认hello time和dead time数值。 4.2、ISIS快速收敛配置 前面BFD检测已经占用了150ms的时间,为了能达到业务指标要求,ISIS的收敛时间不能超过150ms。
BFD addresses these issues and provides fast fault detection independent of media and routing protocols. BFD is useful because it can: Implement light-load fault detection, which takes only milliseconds, enhancing reliability. Quickly detect a broad range of faults, including interface, data link, an...
To avoid packet loss, BFD can be configured for BGP to rapidly detect faults on links between BGP peers and report the faults to BGP for fast BGP route convergence. Table 2 lists the BGP convergence speeds. Table 2 BGP convergence speeds BFD Session Bound Link Fault Detection Mechanism ...
R1 will detect this link failure right away since it’s directly connected to SW1. It will immediately drop the neighbor adjacency. What about R2? R2# Jul 3011:55:14.667: %OSPF-5-ADJCHG: Process 1, Nbr 192.168.12.1 on FastEthernet0/0 from FULL to DOWN,Neighbor Down: Dead timer expired...
如图6所示,Router A与Router B建立BFD会话,双方的Desired Min TX Interval和Required Min RX Interval(下面简称为TX和RX)都为100ms,Detect Mult都为3。根据定时器协商规则,Router A的发送时间间隔为Router A的TX与Router B的RX中的最大值也就是100ms,Router B的发送时间间隔也是100ms,双方的检测超时时间都为...
