Embodiment 1

[0033] The bare metal server VXLAN access method of the present invention comprises the following steps:

[0034] (1) Deploy bare metal servers and VXLAN gateways, such as figure 1 As shown, the ToR switches of all bare metal server cabinets are connected to a spine switch, the VXLAN gateway is connected to the spine switch, and all VXLAN VETPs that communicate with computing nodes and network nodes are built on the VXLAN gateway;

[0035] (2) Configure the IP address of the VXLAN gateway data plane, create a VTEP Schema and start ovsdb-server;

[0036] (3) Start the vtep simulator to monitor changes in the vtep database, and modify the ovs bridge based on changes in the vtep database;

[0037] (4) Use ovsdb-client to connect to the data plane IP of the VXLAN gateway to verify that ovsdb-server can correctly handle VTEP;

[0038] (5) Install networking-l2gw on the network node and enable l2gw service on the neutron server;

[0039] (6) Create a neutron network and subnet, c...

Embodiment 2

[0049] An apparatus according to the present invention includes: at least one memory and at least one processor; the at least one memory is used to store a machine-readable program; the at least one processor is used to call the machine-readable program to execute the embodiment 1 Publicly available bare metal server VXLAN access method.

Embodiment 3

[0051] In a computer-readable medium of the present invention, computer instructions are stored on the above-mentioned computer-readable medium, and when the above-mentioned computer instructions are executed by a processor, the processor is made to execute the method for VXLAN access of a bare metal server disclosed in Embodiment 1 . Specifically, a system or device equipped with a storage medium may be provided, on which a software program code for realizing the functions of any of the above embodiments is stored, and the computer (or CPU or MPU of the system or device) ) to read and execute the program code stored in the storage medium.

Abstract

The invention discloses a bare metal server VXLAN access method and a computer readable medium, belongs to the technical field of VXLAN access, and aims to solve the technical problem of how to solve ToR switch hard limitation. The method comprises the following steps: deploying a bare metal server and a VXLAN gateway; configuring an IP address of a data plane of a VXLAN gateway, creating a VTEP Schema and starting an ovsdb-server; modifying the ovs bridge based on the change of the vtep database; connecting to a data plane IP of a VXLAN gateway by using an ovsdb-client; installing a networking-l2gw at a network node, and enabling the network node to enable a l2gwservice in a network server; and verifying the connectivity of the virtual machine and the bare metal server.

Description

technical field [0001] The invention relates to the technical field of VXLAN access, in particular to a VXLAN access method and a computer-readable medium of a bare metal server. Background technique [0002] Now the BMS is basically connected to the virtual machine network through the ToR switch and the VXLAN VETP of the computing node where the virtual machine is located to establish a peer-to-peer VLAN VTEP. The BMS uses DHCP to obtain an IP address from the subnet managed by neutron. Therefore, the BMS The connected ToR switch also needs to establish a peer-to-peer VXLAN VTEP with the neutron DHCP server (usually a neutronserver or SNAT node). Since the ToR switch uses hardware to implement VXLAN acceleration, there is a hard limit on the maximum number of allowed VXLAN interfaces. For ultra-large-scale In the data center, VXLAN VTEP using ToR switches as bare metal is not scalable. In addition, networking-l2gw uses the OVSDB protocol to configure the hardware ToR switc...
