Abstract: A method performed by a network device may include assembling a multiprotocol label switching (MPLS) echo request, the echo request including an instruction for a transit node to forward the echo request via a bypass path associated with the transit node, and an instruction for an egress node to send an echo reply indicating that the echo request was received on the bypass path. The method may also include sending the MPLS echo request over a functioning label switched path (LSP).

Abstract translation: 由网络设备执行的方法可以包括组合多协议标签交换（MPLS）回波请求，所述回应请求包括用于传输节点的指令，以经由与所述传输节点相关联的旁路路径来转发所述回声请求，以及用于 出口节点发送回应应答，指示在旁路路径上接收到回应请求。 该方法还可以包括通过功能标签交换路径（LSP）发送MPLS回应请求。
