1、配置双网卡绑定(bond0)

# cat ifcfg-em1
DEVICE=em1
NAME=em1
TYPE=Ethernet
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes

# cat ifcfg-em2
DEVICE=em1
NAME=em1
TYPE=Ethernet
BOOTPROTO=none
ONBOOT=yes
MASTER=bond0
SLAVE=yes

#cat ifcfg-bond0
DEVICE=bond0
NAME=bond0
TYPE=Bond
BONDING_MASTER=yes
BOOTPROTO=static
IPADDR=10.2**.32.202
NETMASK=255.255.255.0
GATEWAY=10.2**.32.254
DNS1=8.8.8.8
DNS2=8.8.4.4
ONBOOT=yes  
BONDING_OPTS="mode=802.3ad miimon=100 lacp_rate=fast  xmit_hash_policy=layer2+3"

2、配置双Bond（bond0和bond1）

# more ifcfg-p2p1
TYPE=Ethernet
BOOTPROTO=none
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME=p2p1
UUID=1811a08c-e10e-4423-9499-a5de22625b81
DEVICE=p2p1
ONBOOT=yes
MASTER=bond0
SLAVE=yes

# more ifcfg-p3p1
TYPE=Ethernet
BOOTPROTO=none
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME=p3p1
UUID=8226fa10-8731-4e92-b4a5-8531c4bd45b5
DEVICE=p3p1
ONBOOT=yes
MASTER=bond0
SLAVE=yes

# more ifcfg-p2p2
TYPE=Ethernet
BOOTPROTO=none
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME=p2p2
UUID=b75fc6a8-79f4-4bf5-a9ca-87876db8c648
DEVICE=p2p2
ONBOOT=yes
MASTER=bond1
SLAVE=yes

# more ifcfg-p3p2
TYPE=Ethernet
BOOTPROTO=none
DEFROUTE=yes
PEERDNS=yes
PEERROUTES=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_PEERDNS=yes
IPV6_PEERROUTES=yes
IPV6_FAILURE_FATAL=no
NAME=p3p2
UUID=e1d2939a-00d9-4dce-a27a-c15ec6e3e2ac
DEVICE=p3p2
ONBOOT=yes
MASTER=bond1
SLAVE=yes

# more ifcfg-bond0
DEVICE=bond0
NAME=bond0
BONDING_MASTER=yes
BOOTPROTO=none
IPADDR=10.2**.99.11
NETMASK=255.255.255.0
GATEWAY=10.2**.99.254
DNS1=8.8.8.8
DNS2=8.8.4.4
ONBOOT=yes
NM_CONTROLLED=no
BONDING_OPTS="mode=802.3ad miimon=100 lacp_rate=fast"

# more ifcfg-bond1
DEVICE=bond1
NAME=bond1
BONDING_MASTER=yes
BOOTPROTO=none
IPADDR=10.2**.98.11
NETMASK=255.255.255.0
GATEWAY=10.2**.98.254
ONBOOT=yes
NM_CONTROLLED=no
BONDING_OPTS="mode=802.3ad miimon=100 lacp_rate=fast"

3、配置Vlan

（需要将上面配置中bond0和bond1中ip地址注释掉）

# more ifcfg-bond0.198 
DEVICE=bond0.198
NAME=bond0.198
BOOTPROTO=static
IPADDR=10.2**.98.11
NETMASK=255.255.255.0
GATEWAY=10.2**.98.254
ONBOOT=yes
NM_CONTROLLED=no
VLAN=yes

[root@dmzkvm13 network-scripts]# more ifcfg-bond1.180 
DEVICE=bond1.180
NAME=bond1.180
BOOTPROTO=none
ONBOOT=yes
NM_CONTROLLED=no
VLAN=yes

4、配置Bridge

# more ifcfg-bond0.198 
DEVICE=bond0.198
NAME=bond0.198
BOOTPROTO=none
ONBOOT=yes
NM_CONTROLLED=no
VLAN=yes
BRIDGE=br198

# more ifcfg-bond1.180 
DEVICE=bond1.180
NAME=bond1.180
BOOTPROTO=none
ONBOOT=yes
NM_CONTROLLED=no
VLAN=yes
BRIDGE=br180

# more ifcfg-br198 
DEVICE=br198
NAME=br198
TYPE=Bridge
BOOTPROTO=static
IPADDR=10.2**.98.11
NETMASK=255.255.255.0
GATEWAY=10.2**.98.254
ONBOOT=yes
NM_CONTROLLED=no
DELAY=0
VLAN=yes

# more ifcfg-br180
DEVICE=br180
NAME=br180
TYPE=Bridge
BOOTPROTO=none
ONBOOT=yes
NM_CONTROLLED=no
DELAY=0
VLAN=yes
