一.子网划分

1>.对nat网络进行子网划分

2>.对仅主机网络进行子网划分

二.添加四块网卡并配置bond模式

1>.添加四块网卡

2>.对四块网卡进行配置

[root@openstack.yinzhengjie.org.cn ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0 
BOOTPROTO=static
NAME=eth0
DEVICE=eth0
ONBOOT=yes
NM_CONTROLLED=no
MASTER=bond0
USERCTL=no
SLAVE=yes
[root@openstack.yinzhengjie.org.cn ~]# 
[root@openstack.yinzhengjie.org.cn ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth1
TYPE=Ethernet
BOOTPROTO=static
NAME=eth1
DEVICE=eth1
ONBOOT=yes
NM_CONTROLLED=no
MASTER=bond1
USERCTL=no
SLAVE=yes
[root@openstack.yinzhengjie.org.cn ~]# 
[root@openstack.yinzhengjie.org.cn ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth2
TYPE=Ethernet
BOOTPROTO=static
NAME=eth2
DEVICE=eth2
ONBOOT=yes
NM_CONTROLLED=no
MASTER=bond0
USERCTL=no
SLAVE=yes
[root@openstack.yinzhengjie.org.cn ~]# 
[root@openstack.yinzhengjie.org.cn ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth3 
TYPE=Ethernet
BOOTPROTO=static
NAME=eth3
DEVICE=eth3
ONBOOT=yes
NM_CONTROLLED=no
MASTER=bond1
USERCTL=no
SLAVE=yes
[root@openstack.yinzhengjie.org.cn ~]# 
[root@openstack.yinzhengjie.org.cn ~]#

3>.配置bond卡

[root@openstack.yinzhengjie.org.cn ~]# cat /etc/sysconfig/network-scripts/ifcfg-bond0 
TYPE=Ethernet
BOOTPROTO=static
DEVICE=bond0
ONBOOT=yes
BONDING_MASTER=yes
BONDING_OPTS="miimon=100 mode=1"
IPADDR=192.168.7.111
NETMASK=255.255.248.0
GATEWAY=192.168.7.254
DNS1=192.168.7.254
[root@openstack.yinzhengjie.org.cn ~]# 
[root@openstack.yinzhengjie.org.cn ~]# cat /etc/sysconfig/network-scripts/ifcfg-bond1
TYPE=Ethernet
BOOTPROTO=static
NAME=bond1
DEVICE=bond1
ONBOOT=yes
BONDING_MASTER=yes
BONDING_OPTS="miimon=100 mode=1"
IPADDR=172.30.7.111
NETMASK=255.255.248.0
[root@openstack.yinzhengjie.org.cn ~]# 
[root@openstack.yinzhengjie.org.cn ~]#

三.验证bond模式

1>.查看IP地址信息

2>.将eth3网卡关闭

[root@openstack.yinzhengjie.org.cn ~]# ifconfig eth3 down
[root@openstack.yinzhengjie.org.cn ~]# 
[root@openstack.yinzhengjie.org.cn ~]# ip a

    inet6 fe80::20c:29ff:fe4a:5778/64 scope link tentative dadfailed 
       valid_lft forever preferred_lft forever

3>.验证外网可以ping通
