openvswitch 使用记录（二）--vlan 环境搭建（1）

ovs-br1 即host1环境

 

host1 上ovs-br1创建过程

1、查看物理网卡

[root@localhost openvswitch-2.12.0]# ifconfig

enp2s0: flags=4163  mtu 1500

        inet 10.20.42.99  netmask 255.255.255.0  broadcast 10.20.42.255

        inet6 fe80::20b:2fff:fe17:4706  prefixlen 64  scopeid 0x20

        ether 00:0b:2f:17:47:06  txqueuelen 1000  (Ethernet)

        RX packets 74939  bytes 72871505 (69.4 MiB)

        RX errors 0  dropped 0  overruns 0  frame 0

        TX packets 6264  bytes 473439 (462.3 KiB)

        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

 

[root@localhost openvswitch-2.12.0]# ovs-vsctl show

c41a7ff7-3835-4d77-8870-e9210053cb86

ovs_version: "2.12.0"

2、添加ovs-br1网桥

[root@localhost openvswitch-2.12.0]# ovs-vsctl add-br ovs-br1

[root@localhost openvswitch-2.12.0]# ovs-vsctl show

c41a7ff7-3835-4d77-8870-e9210053cb86

    Bridge "ovs-br1"

        Port "ovs-br1"

            Interface "ovs-br1"

                type: internal

    ovs_version: "2.12.0"

3、添加端口（物理网卡）添加到ovs-br1中

[root@localhost openvswitch-2.12.0]# ovs-vsctl add-port ovs-br1 enp2s0

注意：此时可能网络无法连接外网，如果需要连接外网的话需要如下步骤：

[root@localhost openvswitch-2.12.0]# ifconfig enp2s0 0

[root@localhost openvswitch-2.12.0]# killall dhclient

[root@localhost ext_tools]# ifconfig ovs-br1 up

[root@localhost openvswitch-2.12.0]# dhclient ovs-br1

[root@localhost openvswitch-2.12.0]# ifconfig ovs-br1

ovs-br1: flags=4163  mtu 1500

        inet 10.20.42.99  netmask 255.255.255.0  broadcast 10.20.42.255

        inet6 fe80::d85e:7dff:fea4:de4a  prefixlen 64  scopeid 0x20

        ether 00:0b:2f:17:47:06  txqueuelen 1000  (Ethernet)

        RX packets 206  bytes 26321 (25.7 KiB)

        RX errors 0  dropped 0  overruns 0  frame 0

        TX packets 49  bytes 8536 (8.3 KiB)

        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

此时可以连接外网

[root@localhost ext_tools]# ping www.baidu.com

PING www.a.shifen.com (61.135.169.121) 56(84) bytes of data.

64 bytes from 61.135.169.121: icmp_seq=1 ttl=54 time=1.48 ms

64 bytes from 61.135.169.121: icmp_seq=2 ttl=54 time=1.56 ms

64 bytes from 61.135.169.121: icmp_seq=3 ttl=54 time=1.44 ms

 

[root@localhost openvswitch-2.12.0]# ovs-vsctl show

c41a7ff7-3835-4d77-8870-e9210053cb86

    Bridge "ovs-br1"

        Port "ovs-br1"

            Interface "ovs-br1"

                type: internal

        Port "enp2s0"

            Interface "enp2s0"

    ovs_version: "2.12.0"

[root@localhost openvswitch-2.12.0]#

 

4、向网桥ovs-br1中添加vlan端口p10 vid为10

[root@localhost openvswitch-2.12.0]# ovs-vsctl add-port ovs-br1 p10 tag=10 -- set interface p10 type=internal

5、向网桥ovs-br1中添加vlan端口p20 vid为20

[root@localhost openvswitch-2.12.0]# ovs-vsctl add-port ovs-br1 p20 tag=20 -- set interface p20 type=internal

[root@localhost openvswitch-2.12.0]# ovs-vsctl show

c41a7ff7-3835-4d77-8870-e9210053cb86

    Bridge "ovs-br1"

        Port "p20"

            tag: 20

            Interface "p20"

                type: internal

        Port "p10"

            tag: 10

            Interface "p10"

                type: internal

        Port "ovs-br1"

            Interface "ovs-br1"

                type: internal

        Port "enp2s0"

            Interface "enp2s0"

    ovs_version: "2.12.0"

 

注意：Port "enp2s0" 默认为trunk端口，允许所有的vlan id通过

 

 

6、创建vm1网卡及分配ip地址

 

 

 

 

[loongson@localhost ~]$ ifconfig eth0

eth0: flags=4163  mtu 1500

        inet 192.168.1.2  netmask 255.255.255.0  broadcast 192.168.1.255

        inet6 fe80::5054:ff:feca:274f  prefixlen 64  scopeid 0x20

        ether 52:54:00:ca:27:4f  txqueuelen 1000  (Ethernet)

        RX packets 0  bytes 0 (0.0 B)

        RX errors 0  dropped 0  overruns 0  frame 0

        TX packets 21  bytes 2638 (2.5 KiB)

        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

 

2、vm2网卡创建以及ip地址配置（步骤同上）

 

 

 

[loongson@localhost ~]$ ifconfig eth0

eth0: flags=4163  mtu 1500

        inet 192.168.1.3  netmask 255.255.255.0  broadcast 192.168.1.255

        inet6 fe80::5054:ff:feea:f052  prefixlen 64  scopeid 0x20

        ether 52:54:00:ea:f0:52  txqueuelen 1000  (Ethernet)

        RX packets 7  bytes 572 (572.0 B)

        RX errors 0  dropped 0  overruns 0  frame 0

        TX packets 29  bytes 2018 (1.9 KiB)

        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

到此为止 host1 上的vm1和vm2搭建完成

host2搭建过程看下一篇文章openvswitch 使用记录（二）--vlan 环境搭建（2）

https://mp.csdn.net/console/editor/html/104468102

--------------------------------------------------------------------------

等待host2上环境搭建完成后测试结果

验证结果如下

vm1----ping ---->vm3、vm4    以及vm1---ping--->vm2、vm5、vm6

[loongson@localhost ~]$ ifconfig eth0

eth0: flags=4163  mtu 1500

        inet 192.168.1.2  netmask 255.255.255.0  broadcast 192.168.1.255

        inet6 fe80::5054:ff:feca:274f  prefixlen 64  scopeid 0x20

        ether 52:54:00:ca:27:4f  txqueuelen 1000  (Ethernet)

        RX packets 36  bytes 2806 (2.7 KiB)

        RX errors 0  dropped 0  overruns 0  frame 0

        TX packets 58  bytes 5396 (5.2 KiB)

        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
