Embodiment Construction

[0109] The embodiment of the present application provides a message detection method, a method for establishing a connectivity negotiation relationship, and related equipment, which can be applied to EVPN-VXLAN dual-homing and dual-active scenarios in the case of anycast, so that the first PE can determine the Test results.

[0110] In order to better understand the packet detection method in the embodiment of the present application, the following describes the application scenarios of the embodiment of the present application.

[0111] CE and PE. CE is located at the customer site. In the network, it is a VPN device directly facing users and connected to PE; PE is located at the edge of the operator's network. A VPN device connected to multiple CEs.

[0112] VXLAN is a network virtualization technology. By encapsulating the data packets sent by the virtual machine in the user datagram protocol (UDP), and using the IP or MAC of the physical network for encapsulation, and the...

Abstract

The embodiment of the invention discloses a message detection method which can be applied to the field of communication. The method comprises the steps that a first PE sends a detection message to a second PE, the detection message is used for enabling the second PE to generate a response message, and the detection message comprises a bypass VXLAN tunnel source IP address; the first PE receives a response message for the detection message through the bypass VXLAN tunnel, wherein the response message comprises a bypass VXLAN tunnel source IP address; the first PE obtains a detection result from the response message. According to the embodiment of the invention, the first PE can receive the response message, and therefore the first PE can obtain the detection result.

Description

technical field [0001] The embodiments of the present application relate to the field of communications, and in particular, to a message detection method, a method for establishing a connectivity negotiation relationship, and related equipment. Background technique [0002] Ethernet virtual private network (Ethernet virtual private network, EVPN) is a layer 2 virtual private network (virtual private network, VPN) technology, and the control plane adopts multiprotocol-border gateway protocol (MP-BGP) to notify EVPN For routing information, the data plane forwards packets in a virtual extensible local area network (virtual extensible local area network, VXLAN) encapsulation manner. [0003] In anycast dual-homing dual-active access scenarios, the first customer edge device (customer edge device, CE) dual-homes to the first provider edge device (provider edge device, PE) and the third PE, and the first PE and the second PE VXLAN tunnels are established between the two PEs, and...
