此产品的文档集力求使用非歧视性语言。在本文档集中,非歧视性语言是指不隐含针对年龄、残障、性别、种族身份、族群身份、性取向、社会经济地位和交叉性的歧视的语言。由于产品软件的用户界面中使用的硬编码语言、基于 RFP 文档使用的语言或引用的第三方产品使用的语言,文档中可能无法确保完全使用非歧视性语言。 深入了解思科如何使用包容性语言。
思科采用人工翻译与机器翻译相结合的方式将此文档翻译成不同语言,希望全球的用户都能通过各自的语言得到支持性的内容。 请注意:即使是最好的机器翻译,其准确度也不及专业翻译人员的水平。 Cisco Systems, Inc. 对于翻译的准确性不承担任何责任,并建议您总是参考英文原始文档(已提供链接)。
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。
思科建议您了解Cisco SDWAN解决方案。
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。
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 |
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。
