Title
(EN) Method of configuring seamless bidirectional forwarding detection (SBFD) mechanism and device
(ZH) 配置无缝双向转发检测SBFD机制的方法和装置
Abstract
(EN)
The invention provides a method of configuring a seamless bidirectional forwarding detection (SBFD) mechanism and device. The SBFD mechanism is configured for a forwarding node through a controller, dynamic configuration of the SBFD mechanism can be realized, and a tunnel is protected. The method comprises steps: the controller determines the SBFD configuration information according to the configuration state of the SBFD mechanism of a first forwarding node in multiple forwarding nodes, wherein the SBFD configuration information comprises the information needed to configure an SBFD instance associated with a segment routing (SR) service; and the controller transmits a boundary gateway protocol (BGP) message to the first forwarding node, wherein the BGP message carries the SBFD configuration information.

(ZH)
本申请提供了一种配置无缝双向转发检测SBFD机制的方法和装置,通过控制器为转发节点配置SBFD机制,能够实现SBFD机制的动态配置,为隧道提供保护。该方法包括:控制器根据多个转发节点中的第一转发节点的SBFD机制配置状态,确定SBFD配置信息,所述SBFD配置信息中包括:配置与段路由SR业务相关联的SBFD实例所需要的信息;所述控制器向所述第一转发节点发送边界网关协议BGP报文,所述BGP报文中携带所述SBFD配置信息。
