Build Vxlan environment with CentOS Linux Bridge

One Basic Environment
Use VMware virtual two Linux machines. The CentOS 7,linux kernel is as follows:
4.5.3-1.el7.elrepo.x86_64
If the kernel version is too low, Vxlan is not supported. Kernel upgrades can be done with commands

RPM--import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org

RPM-UVH Http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpmyum--enablerepo=elrepo-kernel Install  Kernel-ml-devel kernel-ml-y

Reboot to select New kernel after upgrade.

Second, the Group Network Diagram

Two virtual machines VM1 and vm2,eth2 are network cards on the virtual machine. VXLAN10 is a virtual network card that is created to handle Vxlan. Veth1 and Veth0 are a pair of virtual ports that are created. BR-VX is the network bridge that is created.
Third, configuration commands
VM1:

#创建网桥br-VX and make it upbrctl addbr BR-VXIP link Set br-vx up# add a virtual network card of type Vxlan,vni-id 100 with the name Vxlan10, indicating that the peer address is 192.168.233.190 , # (this address is VM2 's eth2 address) out interface for the ETH2IP link add vxlan10 type Vxlan ID of the remote 192.168.233.190 dstport 4789 dev eth2ip link se T vxlan10 up# add vxlan10 to the bridge brctl addif br-vx vxlan10# Create a pair of virtual network cards, set the Veth0 address to 192.167.1.6, and bind the veth1 to the bridge BR-VX. Messages sent from veth0# will be sent to Veth1, as veth1 in the bridge will be entered into VXLAN10 via the Vxlan Tunnel sent to the peer IP link Add type vethifconfig veth0 192.167.1.6/24 Upifconfig Veth0 MTU 1450ifconfig veth1 upifconfig veth1 MTU 1450brctl addif BR-VX veth1

VM2:

#创建网桥br-VX and make it upbrctl addbr BR-VXIP link Set br-vx up# add a virtual network card of type Vxlan,vni-id 100 with the name Vxlan10, indicating that the peer address is 192.168.233.180 , # (this address is VM2 's eth2 address) out interface for the ETH2IP link add vxlan10 type Vxlan ID of the  remote 192.168.233.180 dstport 4789 Dev Eth2ip Lin K Set Vxlan10 up# add Vxlan10 to the bridge brctl addif br-vx vxlan10# Create a pair of virtual network cards, set the address of the Veth0 to 192.167.1.7, and bind the veth1 to the bridge BR-VX. Messages sent from veth0# will be sent to Veth1, as veth1 in the bridge will be entered into VXLAN10 via the Vxlan Tunnel sent to the peer IP link Add type vethifconfig veth0 192.167.1.7/24 Upifconfig Veth0 MTU 1450ifconfig veth1 upifconfig veth1 MTU 1450brctl addif BR-VX veth1

Four Verify
After building, you can use the ping command on the VM1 to verify: Vm1:ping 192.167.1.7, through the tcpdump grasp the message to see the structure.
