配置BFD Link-bundle会话必须指定源IPv4地址,该地址为本端三层Eth-Trunk接口的地址。 若指定unshared-mode,则link-bundle会话为非共享模式,link-bundle会话与检测相同链路的动态会话不进行共享,两种会话相互独立。 若不指定unshared-mode,则link-bundle会话为共享模式,这种模式下link-bundle会话与检测相同链路的动态会话...
如果BFD for Link-bundle没有子会话,则主会话状态为Down,通告给上层应用的状态为Unknown。 如果Eth-Trunk下仅有一个成员接口,其对应的子会话状态为Up,该成员口退出Eth-Trunk,则主会话状态为Down。 主会话的本地标识符使用特殊的标识符分配区间:0x00100000–0x00103fff,不占用原有BFD会话标识符区间。由于主会话不...
2、BFD for Link-bundle:(ETH-TRUNK为三层口场景)背景及原理与BFD for Perlink一样;BFD for Link-bundle会话由一个主会话以及多个子会话组成,•主会话负责为Eth-Trunk下每一个成员接口创建一个BFD子会话,以及汇总子会话的检测结果并对Eth-Trunk链路的状态做出最终判断;只要有一个子会话的状态为Up,主会话状态就...

Each bundle member link runs its own BFD session. In the above figure, we will have 4 total BFD sessions running (1 session per member link). BFD Client: bundlemgr, i.e. down BFD session on a specific member link can potentially bring down the whole bundle interface ...
BFD for IPv6 static routes that have link-local address as the next-hop is not supported For BFD on bundle member links, only a single BFD session for each bundle member link is created, monitored, and maintained for the IPv4 addressing type only. IPv6 ...

To enable fast detection of link failure in a port channel, BFD sessions are run on every member link of the port channel. The BFD session that is mapped to a member link is referred to as a micro-BFD session. The micro-BFD sessions on the member links ar...
