组网图形
图1 配置通过流策略实现VLAN间三层隔离组网图
如图一所示,为了通信的安全性,某公司将访客、员工、服务器分别划分到VLAN10、VLAN20、VLAN30中。公司希望:
可采用如下思路配置通过流策略实现VLAN间互访控制:
1. 配置VLAN并将各接口加入VLAN,使员工、服务器、访客间二层隔离。
2. 配置VLANIF接口及其IP地址,使员工、服务器、访客间可三层互通。
3. 配置上行路由,使员工、服务器、访客均可通过Switch访问Internet。
4. 配置并应用流策略,使员工A可以访问服务器区的所有资源,其他员工只能访问服务器A的21端口,且只允许员工访问服务器;使访客只能访问Internet。
1. 配置VLAN并将各接口加入VLAN,使员工、服务器、访客间二层隔离
# 在Switch_1上创建VLAN10,并将接口GE0/0/1以Untagged方式加入VLAN10,接口GE0/0/2以Tagged方式加入VLAN10。Switch_2和Switch_3的配置与Switch_1类似,不再赘述。
<HUAWEI> system-view [HUAWEI] sysname Switch_1 [Switch_1] vlan batch 10 [Switch_1] interface gigabitethernet 0/0/1 [Switch_1-GigabitEthernet0/0/1] port link-type access [Switch_1-GigabitEthernet0/0/1] port default vlan 10 [Switch_1-GigabitEthernet0/0/1] quit [Switch_1] interface gigabitethernet 0/0/2 [Switch_1-GigabitEthernet0/0/2] port link-type trunk [Switch_1-GigabitEthernet0/0/2] port trunk allow-pass vlan 10 [Switch_1-GigabitEthernet0/0/2] quit
# 在Switch_4上创建VLAN10、VLAN20、VLAN30、VLAN100,并配置接口GE0/0/1~GE0/0/4分别以Tagged方式加入VLAN10、VLAN20、VLAN30、VLAN100。
<HUAWEI> system-view [HUAWEI] sysname Switch_4 [Switch_4] vlan batch 10 20 30 100 [Switch_4] interface gigabitethernet 0/0/1 [Switch_4-GigabitEthernet0/0/1] port link-type trunk [Switch_4-GigabitEthernet0/0/1] port trunk allow-pass vlan 10 [Switch_4-GigabitEthernet0/0/1] quit [Switch_4] interface gigabitethernet 0/0/2 [Switch_4-GigabitEthernet0/0/2] port link-type trunk [Switch_4-GigabitEthernet0/0/2] port trunk allow-pass vlan 20 [Switch_4-GigabitEthernet0/0/2] quit [Switch_4] interface gigabitethernet 0/0/3 [Switch_4-GigabitEthernet0/0/3] port link-type trunk [Switch_4-GigabitEthernet0/0/3] port trunk allow-pass vlan 30 [Switch_4-GigabitEthernet0/0/3] quit [Switch_4] interface gigabitethernet 0/0/4 [Switch_4-GigabitEthernet0/0/4] port link-type trunk [Switch_4-GigabitEthernet0/0/4] port trunk allow-pass vlan 100 [Switch_4-GigabitEthernet0/0/4] quit
2. 配置VLANIF接口及其IP地址,使员工、服务器、访客间可以三层互通
# 在Switch_4上创建VLANIF10、VLANIF20、VLANIF30、VLANIF100,并分别配置其IP地址为10.1.1.1/24、10.1.2.1/24、10.1.3.1/24、10.1.100.1/24。
[Switch_4] interface vlanif 10 [Switch_4-Vlanif10] ip address 10.1.1.1 24 [Switch_4-Vlanif10] quit [Switch_4] interface vlanif 20 [Switch_4-Vlanif20] ip address 10.1.2.1 24 [Switch_4-Vlanif20] quit [Switch_4] interface vlanif 30 [Switch_4-Vlanif30] ip address 10.1.3.1 24 [Switch_4-Vlanif30] quit [Switch_4] interface vlanif 100 [Switch_4-Vlanif100] ip address 10.1.100.1 24 [Switch_4-Vlanif100] quit
3. 配置上行路由,使员工、服务器、访客均可通过Switch访问Internet。
# 在Switch_4上配置OSPF基本功能,发布用户网段以及Switch_4与Router之间的互联网段。
[Switch_4] ospf [Switch_4-ospf-1] area 0 [Switch_4-ospf-1-area-0.0.0.0] network 10.1.1.0 0.0.0.255 [Switch_4-ospf-1-area-0.0.0.0] network 10.1.2.0 0.0.0.255 [Switch_4-ospf-1-area-0.0.0.0] network 10.1.3.0 0.0.0.255 [Switch_4-ospf-1-area-0.0.0.0] network 10.1.100.0 0.0.0.255 [Switch_4-ospf-1-area-0.0.0.0] quit [Switch_4-ospf-1] quit
说明:
Router上需要进行如下配置:
具体配置请参见使用设备的产品文档,本文不再赘述。
4. 配置并应用流策略,控制员工、访客、服务器之间的访问
a. 通过ACL定义每个流
# 在Switch_4上配置ACL 3000,禁止访客访问员工区和服务器区。
[Switch_4] acl 3000 [Switch_4-acl-adv-3000] rule deny ip destination 10.1.2.1 0.0.0.255 [Switch_4-acl-adv-3000] rule deny ip destination 10.1.3.1 0.0.0.255 [Switch_4-acl-adv-3000] quit
# 在Switch_4上配置ACL 3001,使员工A可以访问服务器区的所有资源,其他员工只能访问服务器A的21端口。
[Switch_4] acl 3001 [Switch_4-acl-adv-3001] rule permit ip source 10.1.2.2 0 destination 10.1.3.1 0.0.0.255 [Switch_4-acl-adv-3001] rule permit tcp destination 10.1.3.2 0 destination-port eq 21 [Switch_4-acl-adv-3001] rule deny ip destination 10.1.3.1 0.0.0.255 [Switch_4-acl-adv-3001] quit
b. 配置流分类,区分不同的流
# 在Switch_4上创建流分类c_custom、c_staff,并分别配置匹配规则3000、3001。
[Switch_4] traffic classifier c_custom [Switch_4-classifier-c_custom] if-match acl 3000 [Switch_4-classifier-c_custom] quit [Switch_4] traffic classifier c_staff [Switch_4-classifier-c_staff] if-match acl 3001 [Switch_4-classifier-c_staff] quit
c. 配置流行为,指定流动作
# 在Switch_4上创建流行为b1,并配置允许动作。
[Switch_4] traffic behavior b1 [Switch_4-behavior-b1] permit [Switch_4-behavior-b1] quit
d. 配置流策略,关联流分类和流行为
# 在Switch_4上创建流策略p_custom、p_staff,并分别将流分类c_custom、c_staff与流行为b1关联。
[Switch_4] traffic policy p_custom [Switch_4-trafficpolicy-p_custom] classifier c_custom behavior b1 [Switch_4-trafficpolicy-p_custom] quit [Switch_4] traffic policy p_staff [Switch_4-trafficpolicy-p_staff] classifier c_staff behavior b1 [Switch_4-trafficpolicy-p_staff] quit
e. 应用流策略,实现员工、访客、服务器之间的访问控制
# 在Switch_4上,分别在VLAN10、VLAN20的入方向应用流策略p_custom、p_staff。
[Switch_4] vlan 10 [Switch_4-vlan10] traffic-policy p_custom inbound [Switch_4-vlan10] quit [Switch_4] vlan 20 [Switch_4-vlan20] traffic-policy p_staff inbound [Switch_4-vlan20] quit
5. 验证配置结果
配置访客A的IP地址为10.1.1.2/24,缺省网关为VLANIF10接口的IP地址10.1.1.1;配置员工A的IP地址为10.1.2.2/24,缺省网关为VLANIF20接口的从IP地址10.1.2.1;配置员工B的IP地址为10.1.2.3/24,缺省网关为VLANIF20接口的从IP地址10.1.2.1;配置服务器A的IP地址为10.1.3.2/24,缺省网关为VLANIF30接口的从IP地址10.1.3.1。
