On host2 ovs-br2 creation process:
The initial state
[root@localhost out]# ovs-vsctl show
06e749d9-0c1e-4b72-bcbc-94db1b7111dd
ovs_version: "2.12.0"
1, was added ovs-br2 bridge on host2
[root@localhost out]# ovs-vsctl add-br ovs-br2
2, add port (physical NIC) to ovs-br2
[Root @ localhost out] # OVS vsctl add port OVS-Br 2 enp6s0
Note: At this time, the network may be unable to access external network For Internet treated as follows:
[root@localhost out]# ifconfig enp6s0 0
[root@localhost out]# killall dhclient
[root@localhost out]#ifconfig ovs-br2 up
[root@localhost out]#dhclient ovs-br2
View current ovs bridge information
[root@localhost out]# ovs-vsctl show
06e749d9-0c1e-4b72-bcbc-94db1b7111dd
Bridge "ovs-br2"
Port "ovs-br2"
Interface "ovs-br2"
type: internal
Port "enp6s0"
Interface "enp6s0"
ovs_version: "2.12.0"
3, was added to ovs-br2 port 10 to p10 and vid
[root@localhost out]# ovs-vsctl add-port ovs-br2 p10 tag=10 -- set interface p10 type=internal
4, p20 and the add port is provided to vid for 20 ovs-br2
[root@localhost out]# ovs-vsctl add-port ovs-br2 p20 tag=20 -- set interface p20 type=internal
Check that the bridge information at this time has added two vlan port,
[root@localhost out]# ovs-vsctl show
06e749d9-0c1e-4b72-bcbc-94db1b7111dd
Bridge "ovs-br2"
Port "ovs-br2"
Interface "ovs-br2"
type: internal
Port "p20"
tag: 20
Interface "p20"
type: internal
Port "enp6s0"
Interface "enp6s0"
Port "p10"
tag: 10
Interface "p10"
type: internal
ovs_version: "2.12.0"
Note: Port "enp6s0" default trunk port, allowing all through vlan id
5, the following was added vm3 FIG NIC mode, select p10
The following figure card vm3
Ip address configuration
Vm3 configuration of eth0 ip is 192.168.1.4
[loongson@localhost ~]$ ifconfig
