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

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

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 ~]#

3>.验证外网可以ping通
