example 1

[0082] In Example 1, VTEP1 is used as the first VTEP device, VTEP3 is used as the second VTEP device, VM1 is used as the first host, and AC port 3 is used as the first AC port. Such as image 3 As shown, for AC port 1 in VTEP1: the private network ID configured on AC port 1 is 10, which is the same as the private network ID (the private network ID of VM1) 10 included in the first MAC / IP notification route; AC port 1 is configured The ESI of 1 is the same as the ESI (ESI of AC port 3) 1 included in the first MAC / IP advertisement route; therefore, AC port 1 is the second AC port. For AC port 2 in VTEP1: the private network ID configured on AC port 2 is 20, which is different from the private network ID 10 included in the first MAC / IP notification route, so AC port 2 is not the second AC port.

example 2

[0083] In Example 2, VTEP1 is used as the first VTEP device, VTEP3 is used as the second VTEP device, VM4 is used as the first host, and AC port 4 is used as the first AC port. Such as image 3 As shown, for AC port 1 in VTEP1: the private network ID configured on AC port 1 is 10, which is different from the private network ID (the private network ID of VM4) 30 included in the first MAC / IP advertisement route, so AC port 1 Not the second AC port. For AC port 2 in VTEP1: the private network ID configured on AC port 2 is 20, which is different from the private network ID 30 included in the first MAC / IP notification route, so AC port 2 is not the second AC port.

[0084] Step S13, when the second AC port is found, generate a forwarding entry corresponding to the first host according to the second AC port, and the forwarding entry corresponding to the first host is used for the first When forwarding the message to the first host, the VTEP device determines the second AC port as ...

Abstract

The present invention relates to a routing processing method and device, which are used for a first VTEP device in a multi-homing network, and a first host simultaneously accesses the first VTEP device and the second VTEP device in the multi-homing network, including: Receive the first MAC / IP notification route sent by the second VTEP device; traverse all AC ports associated with the VXLAN identifier in the first VTEP device, and search for all AC ports associated with the VXLAN identifier A second AC port matching the private network identifier and the ESI; when the second AC port is found, a forwarding entry corresponding to the first host is generated according to the second AC port. By generating forwarding entries according to the second AC interface, the routing processing method and device according to the embodiments of the present invention can avoid detour of remote traffic between VTEP devices in the EVPN multi-homing system.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a route processing method and device. Background technique [0002] Ethernet Virtual Private Network (English: Ethernet Virtual Private Network, referred to as: EVPN) is a two-layer VPN technology. In order to improve the reliability of the access side, the protocol stipulates the EVPN multi-homing access network, thereby improving the reliability of service data packets. In EVPN multi-homing networking, a virtual machine (English: Virtual Machine, referred to as: VM) can access different scalable virtual local area network tunnel endpoints (English: VXLAN Tunnel EndPoint, referred to as: VTEP) through multiple links at the same time. equipment. A VM is connected to multiple links of different VTEP devices to form an ES (English: Ethernet Segment, referred to as: Ethernet segment). ESI (English: Ethernet Segment Identifier, referred to as: Ethernet Segment Ident...
