标签：seq ping vlan bytes openvswitch 192.168 64 icmp 搭建
host2上ovs-br2创建过程：
初始状态
[root@localhost out]# ovs-vsctl show
06e749d9-0c1e-4b72-bcbc-94db1b7111dd
ovs_version: "2.12.0"
1、在host2上添加ovs-br2网桥
[root@localhost out]# ovs-vsctl add-br ovs-br2
2、添加端口（物理网卡）到ovs-br2上
[root@localhost out]# ovs-vsctl add-port ovs-br2 enp6s0
注意：此时网络可能无法通往外网如需上网做如下处理：
[root@localhost out]# ifconfig enp6s0 0
[root@localhost out]# killall dhclient
[root@localhost out]#ifconfig ovs-br2 up
[root@localhost out]#dhclient ovs-br2
查看当前ovs网桥信息
[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、向ovs-br2中添加端口p10 并将vid设置为10
[root@localhost out]# ovs-vsctl add-port ovs-br2 p10 tag=10 -- set interface p10 type=internal
4、向ovs-br2中添加端口p20 并将vid设置为20
[root@localhost out]# ovs-vsctl add-port ovs-br2 p20 tag=20 -- set interface p20 type=internal
查看此时网桥信息 此时已经添加2个vlan端口，
[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"
注意：Port "enp6s0" 默认为trunk端口，允许所有的vlan id通过
5、添加vm3网卡模式如下图，选择p10
下图为vm3网卡
配置ip地址
配置vm3的eth0 ip 为 192.168.1.4
[loongson@localhost ~]$ ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.1.4 netmask 255.255.255.0 broadcast 192.168.1.255
inet6 fe80::5054:ff:fef6:d092 prefixlen 64 scopeid 0x20<link>
ether 52:54:00:f6:d0:92 txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 20 bytes 2296 (2.2 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
6、添加vm4网卡模式如下图，选择p10
ip地址如下
[loongson@localhost ~]$ ifconfig eth0
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.1.5 netmask 255.255.255.0 broadcast 192.168.1.255
inet6 fe80::5054:ff:fef0:dcf prefixlen 64 scopeid 0x20<link>
ether 52:54:00:f0:0d:cf txqueuelen 1000 (Ethernet)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 18 bytes 1292 (1.2 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
7、 添加vm5网卡模式如下图，选择p20
查看ip地址
[loongson@localhost ~]$ ifconfig eth0
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.1.6 netmask 255.255.255.0 broadcast 192.168.1.255
inet6 fe80::5054:ff:fe81:9971 prefixlen 64 scopeid 0x20<link>
ether 52:54:00:81:99:71 txqueuelen 1000 (Ethernet)
RX packets 2 bytes 84 (84.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 19 bytes 1354 (1.3 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
8、 添加vm6网卡模式如下图，选择p20
[loongson@localhost ~]$ ifconfig eth0
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 192.168.1.7 netmask 255.255.255.0 broadcast 192.168.1.255
inet6 fe80::5054:ff:fe95:f3fe prefixlen 64 scopeid 0x20<link>
ether 52:54:00:95:f3:fe txqueuelen 1000 (Ethernet)
RX packets 2 bytes 84 (84.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 19 bytes 1354 (1.3 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
