将通信接通
使用dhcp
使用ospf路由
链路聚合

![!\[\](vx_images/209964920256912.png)][2]

二层交换机：
**Sw0**:
```
vlan 10
vlan 20
int f0/1
switchport access vlan 10
int f0/2
switchport mode trunk 
int f0/4
switchport mode trunk 
```
**Sw2**:
```
vlan 10
vlan20
int f0/1
int f0/3
int f0/2
switchport mode trunk 
int f0/4
switchport mode trunk 
```
![!\[\](vx_images/389745520249581.png)][3]
将相应端口设置为trunk模式
**Sw2：**
```
int f0/2
switchport trunk encapsulation dot1q
switchport mode trunk 
int f0/4
switchport trunk encapsulation dot1q
switchport mode trunk 
int range f0/11-12
switchport trunk encapsulation dot1q
switchport mode trunk 
```
**Sw3:**
```
int f0/2
switchport trunk encapsulation dot1q
switchport mode trunk 
int f0/4
switchport trunk encapsulation dot1q
switchport mode trunk 
int range f0/11-12
switchport trunk encapsulation dot1q
switchport mode trunk 
```
创建设置链路聚合
**Sw2:**
```
int range f0/11-12
channel-group 1 mode on
sw t e dot1q 
switchport mode trunk 
spanning-tree vlan 10 priority 0
```
**Sw3:**
```
int range f0/11-12
channel-group 1 mode on
sw t e dot1q 
switchport mode trunk 
spanning-tree vlan 20 priority 0
```

虚拟网关
Sw2：
vlan10:
```
ip address 192.168.10.252 255.255.255.0
standby 10 ip 192.168.10.254
```
vlan20:
```
ip address 192.168.20.252 255.255.255.0
standby 10 ip 192.168.20.254
```
Sw3：
vlan10:
```
ip address 192.168.10.253 255.255.255.0
standby 10 ip 192.168.10.254
```
vlan20:
```
ip address 192.168.20.253 255.255.255.0
standby 10 ip 192.168.20.254
```

**2911**
**dhcp:**
```
ip dhcp pool vlan10
network 192.168.10.0 255.255.255.0
default-router 192.168.10.254
dns-server 192.168.117.117
```
**dhcp2:**
```
ip dhcp pool vlan10
network 192.168.10.0 255.255.255.0
default-router 192.168.10.254
dns-server 192.168.117.117
```

**Sw2:**
```
int vlan 10
ip helper-address 172.16.1.2
int vlan 20
ip helper-address 172.16.1.2
```
**Sw3**
```
int vlan 10
ip helper-address 172.16.2.2
int vlan 20
ip helper-address 172.16.2.2
```

int g0/2
ip add 100.1.1.1 255.255.255.0

int range g0/0-1
ip nat inside

**静态路由：**
```
ip route 0.0.0.0 0.0.0.0 100.1.1.2 //静态路由
default-information originate   //广播到OSPF区域。标记O*E2.
```

**NAT设置**
```
access-list 1 permit 192.168.10.0 0.0.0.255
access-list 1 permit 192.168.20.0 0.0.0.255
int range g0/0-1

ip nat inside source list 1 interface g0/2 overload
```

R1(2911)
```
int g0/0
ip add 100.1.1.2 255.255.255.0
```
