华为策略路由配置实例1、组网需求 图1策略路由组网示例图如上图1所示，公司用户通过Switch双归属到外部网络设备。其中，一条是低速链路，网关为10.1.20.1/24；另外一条是高速链路，网关为10.1.30.1/24。公司希望上送外部网络的报文中，IP优先级为4、5、6、7的报文通过高速链路传输，而IP优先级为0、1、2、3的报文则通过低速链路传输。2、配置思路1、创建VLAN并配置各接口，实现公司和外部网络设备互连。2、配置ACL规则，分别匹配IP优先级4、5、6、7，以及IP优先级0、1、2、3。3、配置流分类，匹配规则为上述ACL规则，使设备可以对报文进行区分。4、配置流行为，使满足不同规则的报文分别被重定向到10.1.20.1/24和10.1.30.1/24。5、配置流策略，绑定上述流分类和流行为，并应用到接口GE2/0/1的入方向上，实现策略路由。3、操作步骤3.1、创建VLAN并配置各接口#在Switch上创建VLAN100和VLAN200。HUAWEIsystem-viewHUAWEIsysname SwitchSwitchvlan batch 100 200#配置Switch上接口GE1/0/1、GE1/0/2和GE2/0/1的接口类型为Trunk，并加入VLAN100和VLAN200。Switchinterface gigabitethernet 1/0/1Switch-GigabitEthernet1/0/1port link-type trunkSwitch-GigabitEthernet1/0/1port trunk allow-pass vlan 100 200Switch-GigabitEthernet1/0/1quitSwitchinterface gigabitethernet 1/0/2Switch-GigabitEthernet1/0/2port link-type trunkSwitch-GigabitEthernet1/0/2port trunk allow-pass vlan 100 200Switch-GigabitEthernet1/0/2quitSwitchinterface gigabitethernet 2/0/1Switch-GigabitEthernet2/0/1port link-type trunkSwitch-GigabitEthernet2/0/1port trunk allow-pass vlan 100 200Switch-GigabitEthernet2/0/1quit配置LSW与Switch对接的接口为Trunk类型接口，并加入VLAN100和VLAN200。#创建VLANIF100和VLANIF200，并配置各虚拟接口IP地址。Switchinterface vlanif 100Switch-Vlanif100ip address 10.1.20.2 24Switch-Vlanif100quitSwitchinterface vlanif 200Switch-Vlanif200ip address 10.1.30.2 24Switch-Vlanif200quit3.2、配置ACL规则#在Switch上创建编码为3001、3002的高级ACL，规则分别为允许IP优先级0、1、2、3和允许IP优先级4、5、6、7的报文通过。Switchacl 3001Switch-acl-adv-3001rule permit ip precedence 0Switch-acl-adv-3001rule permit ip precedence 1Switch-acl-adv-3001rule permit ip precedence 2Switch-acl-adv-3001rule permit ip precedence 3Switch-acl-adv-3001quitSwitchacl 3002Switch-acl-adv-3002rule permit ip precedence 4Switch-acl-adv-3002rule permit ip precedence 5Switch-acl-adv-3002rule permit ip precedence 6Switch-acl-adv-3002rule permit ip precedence 7Switch-acl-adv-3002quit3.3、配置流分类在Switch上创建流分类c1、c2，匹配规则分别为ACL 3001和ACL 3002。Switchtraffic classifier c1 operator andSwitch-classifier-c1if-match acl 3001Switch-classifier-c1quitSwitchtraffic classifier c2 operator andSwitch-classifier-c2if-match acl 3002Switch-classifier-c2quit3.4、配置流行为#在Switch上创建流行为b1、b2，并分别指定重定向到网段10.1.20.1/24和10.1.30.1/24的动作。Switchtraffic behavior b1Switch-behavior-b1redirect ip-nexthop 10.1.20.1Switch-behavior-b1quitSwitchtraffic behavior b2Switch-behavior-b2redirect ip-nexthop 10.1.30.1Switch-behavior-b2quit3.5、配置流策略并应用到接口上#在Switch上创建流策略p1，将流分类和对应的流行为进行绑定。Switchtraffic policy p1Switch-trafficpolicy-p1classifier c1 behavior b1Switch-trafficpolicy-p1classifier c2 behavior b2Switch-trafficpolicy-p1quit#将流策略p1应用到接口GE2/0/1的入方向上。Switchinterface gigabitethernet 2/0/1Switch-GigabitEthernet2/0/1traffic-policy p1 inboundSwitch-GigabitEthernet2/0/1return3.6、验证配置结果#查看ACL规则的配置信息。Switchdisplay acl 3001Advanced ACL 3001, 4 rulesAcls step is 5rule 5 permit ip precedence routine (match-counter 0)rule 10 permit ip precedence priority (match-counter 0)rule 15 permit ip precedence immediate (match-counter 0)rule 20 permit ip precedence flash (match-counter 0)Switchdisplay acl 3002Advanced ACL 3002, 4 rulesAcls step is 5rule 5 permit ip precedence flash-override (match-counter 0)rule 10 permit ip precedence critical (match-counter 0)rule 15 permit ip precedence internet (match-counter 0)rule 20 permit ip precedence network (match-counter 0)#查看流分类的配置信息。Switchdisplay traffic classifier user-defined User Defined Classifier Information: Classifier: c1 Precedence: 5 Operator: AND Rule(s) :if-match acl 3001 Classifier: c2 Precedence: 10 Operator: AND Rule(s) :if-match acl 3002Total classifier number is 2#查看流策略的配置信息。Switchdisplay traffic policy user-defined p1 User Defined Traffic Policy Information: Policy: p1 Classifier: c1 Operator: AND Behavior: b1 Redirect: no forced Redirect ip-nexthop 10.1.20.1 Classifier: c2 Operator: AND Behavior: b2 Redirect: no forced Redirect ip-nexthop 10.1.30.14、配置文件Switch的配置文件#sysname Switch#vlan batch 100 200#acl number 3001rule 5 permit ip precedence routinerule 10 permit ip precedence priorityrule 15 permit ip precedence immediaterule 20 permit ip precedence flash#acl number 3002rule 5 permit ip precedence flash-overriderule 10 permit ip precedence criticalrule 15 permit ip precedence internetrule 20 permit ip precedence network#traffic classifier c1 operator and precedence 5if-match acl 3001traffic classifier c2 operator and precedence 10if-match acl 3002#traffic behavior b1redirect ip-nexthop 10.1.20.1traffic behavior b2redirect ip-nexthop 10.1.30.1#traffic policy p1 match-order configclassifier c1 behavior b1classifier c2 behavior b2#interface Vlanif100ip address 10.1.20.2 255.255.255.0#interface Vlanif200ip address 10.1.30.2 255.255.255.0#interface GigabitEthernet1/0/1port link
