简介
本文档介绍Cisco vEdge路由器上的各种双向转发检测(BFD)抖动原因。
先决条件
要求
思科建议您了解Cisco SDWAN解决方案。
使用的组件
本文档基于运行19.2.1的Cisco云vEdge路由器。
本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您的网络处于活动状态，请确保您了解所有命令的潜在影响。
拓扑概述
本文档不限于任何特定拓扑。
本文档中某些重要组件的IP地址和颜色：
| 组件 | 系统IP | VPN 0 IP /颜色 | VPN 0 IP /颜色 |
| VEDGE-1 | 10.13.13.13 | 192.168.1.4 / mpls | 192.168.2.4 / mpls |
| VEDGE-2 | 10.15.15.15 | 192.168.1.8 /商业互联网 | 192.168.2.8 /商业互联网 |
| vSmart | 10.8.8.8 | 192.168.1.3 /默认 | 不适用 |
| vManage | 10.7.7.7 | 192.168.1.1 /默认 | 不适用 |
BFD状态
Cisco vEdge路由器上“flap-reason”的可能值为：
1.bfd-deleted - BFD关闭，因为控制平面已将其删除。
删除BFD时，您会发出两个通知。一个用于BFD关闭，一个用于BFD删除。
2. timeout — 远程端没有BFD响应。
3. remote-down — 远程端发送了一个BFD数据包，表明它已进入down-state。4.
4.不适用 — 不适用。当首次创建BFD会话和BFD会话启动时，会设置此设置。
场景
场景1.抖动原因：bfd-deleted
在VEDGE-1路由器上执行端口跃点并重现此场景：
