Segmented tracking routing for segmented routing traffic engineering

Segmented tracking routing for segmented routing traffic engineering is described. For example, the ingress device comprises: one or more processors operably coupled to a memory, the one or more processors configured to: in response to a request to verify a connection of a segment routing LSP, configure an FEC stack specifying a stack of segment routing tags of the segment routing LSP; for each of the one or more devices identified from the FEC stack: generating a respective MPLS connection request packet for a respective device identified from an outermost FEC of the FEC stack; sending the MPLS connection request packet to corresponding equipment; receiving an MPLS connection response packet that verifies a connection of the respective device; and in response, updating the FEC stack by removing the outermost FEC identifying the FEC stack of the respective device. 描述了用于分段路由流量工程的分段跟踪路由。例如，入口设备包括：一个或多个处理器，可操作地耦接至存储器，该一个或多个处理器被配置为：响应于验证分段路由LSP的连接的请求，配置指定分段路由LSP的分段路由标签的栈的FEC栈；对于从FEC栈中识别的一个或多个设备中的每个设备：为从FEC栈的最外FEC
