本文配置目标：华为防火墙双机热备，电信和联通双运营商、固定IP接入，华为核心交换机配置VRRP。
为保护客户隐私，电信和联通的IP地址为虚构，如有雷同，纯属巧合。
真实拓扑图如下所示，电信和联通给的掩码都是29，如果掩码都是30，恐怕不能这么连接。
回来用模拟器还原了配置，注意AR3以及下面的两台交换机，是用来模拟运营商接入的，实际环境中只是两个光猫而已。
一、配置模拟运营商接入的设备
1、路由器的配置：
配置各接口IP，并且宣告进OSPF
interface GigabitEthernet0/0/0
ip address 33.1.1.3 255.255.255.0
#
interface GigabitEthernet0/0/1
ip address 34.1.1.3 255.255.255.0
#
interface LoopBack0
ip address 3.3.3.3 255.255.255.255
#
ospf 1 router-id 3.3.3.3
area 0.0.0.0
network 3.3.3.3 0.0.0.0
network 33.1.1.3 0.0.0.0
network 34.1.1.3 0.0.0.0
#
2、交换机SW3的配置：
创建VLAN，配置IP，并且宣告进OSPF
vlan batch 33 130 222
#
interface Vlanif33
ip address 33.1.1.1 255.255.255.0
#
interface Vlanif222
ip address 222.92.76.1 255.255.255.0
#
interface GigabitEthernet0/0/1
port link-type access
port default vlan 222
#
interface GigabitEthernet0/0/2
port link-type access
port default vlan 222
#
interface GigabitEthernet0/0/3
port link-type access
port default vlan 33
#
ospf 1 router-id 1.1.1.1
area 0.0.0.0
network 222.92.76.1 0.0.0.0
network 33.1.1.1 0.0.0.0
#
3、交换机SW4的配置：
vlan batch 34 130
#
interface Vlanif34
ip address 34.1.1.4 255.255.255.0
#
interface Vlanif130
ip address 130.1.1.1 255.255.255.0
#
interface GigabitEthernet0/0/1
port link-type access
port default vlan 130
#
interface GigabitEthernet0/0/2
port link-type access
port default vlan 130
#
interface GigabitEthernet0/0/3
port link-type access
port default vlan 34
#
ospf 1 router-id 4.4.4.4
area 0.0.0.0
network 130.1.1.1 0.0.0.0
network 34.1.1.4 0.0.0.0
#
二、防火墙的配置
以FW1的配置为例说明
1、配置各接口IP
2、配置NAT策略
电信的NAT策略：
联通的NAT策略：
3、配置上网案例策略：
4、配置IP-LINK，也可以在创建默认的路由顺便创建
5、配置默认路由
电信和联通各有一条默认路由
6、配置通向局域网的回程路由
7、配置FW2，过程略，方法同上；
8、在FW1上配置双机热备（主）
9、在FW2上配置双机热备（备）
三、核心交换机和接入交换机的配置
1、核心交换机CE1的配置
vlan batch 9 to 10
#
stp enable
Stp mode mstp
#
stp region-configuration
region-name test
revision-level 1
instance 1 vlan 9 to 10
#
stp instance 1 root primary
#

#
stp region-configuration
region-name test
revision-level 1
instance 1 vlan 9 to 10
active region-configuration
#

#
interface Ethernet0/0/4
port link-type access
port default vlan 10
stp edged-port enable
#
4、接入交换机SW2的配置
和SW1的配置非常接近，就不再重复贴出来了。
四、灾难测试
1、模拟VRRP Master交换机故障
如上图所示，停止CE1交换机后，上网流量切换到右边了；
2、模拟防火墙FW1故障
关停防火墙FW1之后，HRP状态切换了，右侧备机切换为激活状态，上网流量切换到FW2上面了，说明配置正确。
