H3C万兆核心路由器Redirect配置举例

1       组网需求

对从GE3/1/2接口进来的源IP为2.2.2.2的IP报文，从接口GE3/1/2出去，源IP为3.3.3.3的IP报文，从接口GE3/1/3出去。

                        

图1  Redirect配置组网图

2  配置思路

l              配置acl 3000，匹配源ip为2.2.2.2的数据流

l              配置acl 3001，匹配源IP为3.3.3.3的数据

l              配置流分类redirect_class_1，匹配acl 3000

l              配置流分类redirect_class_2，匹配acl 3001

l              配置流行为redirect_class_1，动作为redirect

l              配置流行为redirect_class_2，动作为redirect

l              配置QoS策略redirect_policy，绑定流分类和流行为

l              将QoS策略下发到端口GE3/1/1

3  配置步骤

# 定义ACL 3000，匹配源ip为2.2.2.2的数据流

[H3C] acl number 3000

[H3C-acl-adv-3000] rule 0 permit ip source 2.2.2.2 0

# 定义ACL 3001，匹配源ip为3.3.3.3的数据流

[H3C] acl number 3001

[H3C-acl-adv-3001] rule 0 permit ip source 3.3.3.3 0

# 定义流分类redirect_class_1，匹配acl 3000

[H3C] traffic classifier redirect_class_1

[H3C-classifier-redirect_class_1] if-match acl 3000

# 定义流分类redirect_class_2，匹配acl 3001

[H3C] traffic classifier redirect_class_1

[H3C-classifier-redirect_class_1] if-match acl 3001

# 定义流行为redirect_behavior_1，动作为redirect

[H3C] traffic behavior redirect_behavior_1

[H3C-behavior-redirect_behavior_1] redirect next-hop 20.20.20.0

# 定义流行为redirect_behavior_2，动作为redirect

[H3C] traffic behavior redirect_behavior_2

[H3C-behavior-redirect_behavior_2 ]  redirect next-hop 30.30.30.0

# 定义QoS策略redirect_policy,绑定流行为和流动作

[H3C] qos policy redirect_policy

[H3C-qospolicy-car_policy] classifier redirect_class_1 behavior redirect_behavior_1

[H3C-qospolicy-car_policy] classifier redirect_class_2 behavior redirect_behavior_2

  [H3C] interface GigabitEthernet 3/1/1

[H3C-GigabitEthernet3/1/1] qos apply policy redirect_policy inbound

# 验证配置信息

[H3C-GigabitEthernet3/1/1] display qos policy interface GigabitEthernet 3/1/1

 Interface: GigabitEthernet3/1/1

  Direction: Inbound

  Policy: redirect_policy

   Classifier: redirect_class_1

     Operator: AND

     Rule(s) : If-match acl 3000

     Behavior: redirect_behavior_1

      Redirect enable:

        Redirect type: next-hop

        Redirect destination:

          20.20.20.0

   Classifier: redirect_class_2

     Operator: AND

     Rule(s) : If-match acl 3001

     Behavior: redirect_behavior_2

      Redirect enable:

        Redirect type: next-hop

        Redirect destination:

          30.30.30.0

l              出方向redirect与filter deny，remark qos-local-id，remark local-precedence，remark forwarding-class，mirror，primap color-map-dp，remark dp冲突

l              入方向redirect与filter deny，remark qos-local-id，remark local-precedence，remark forwarding-class冲突，另外，入方向redirect cpu与mirror-to cpu冲突
