1  简介

本文主要介绍策略路由与NQA联动典型配置。

2  配置前提

本文档不严格与具体软、硬件版本对应,如果使用过程中与产品实际情况有差异,请参考相关产品手册,或以设备实际情况为准。

本文档中的配置均是在实验室环境下进行的配置和验证,配置前设备的所有参数均采用出厂时的缺省配置。如果您已经对设备进行了配置,为了保证配置效果,请确认现有配置和以下举例中的配置不冲突。

本文档假设您已了解策略路由和NQA特性。

3  配置举例

3.1  组网需求

图1所示,RouterA到达RouterC的路由下一跳为RouterB,在RouterB上通过策略路由、Track与NQA联动,对到达Router C的链路有效性进行实时判断。

图1 策略路由与NQA联动配置组网图

 

 

3.2  配置思路

·     为实现全网互通,配置路由协议;

·     为监控策略路由,建立NQA测试组;

·     为使能NQA,Track与NQA测试组关联。

3.3  使用版本

本举例是在Release 2317版本上进行配置和验证的。

3.4  配置注意事项

策略路由可以在配置报文的发送接口、缺省发送接口、下一跳、缺省下一跳时与Track项关联,通过Track项的状态来动态地决定策略的可用性。当应用动作增加Track关联后,如果事件发生时Track项状态为positive,则该配置项有效,可以指导转发;事件发生时,Track项状态为negative,则该配置项无效,转发时忽略该配置项。

3.5  配置步骤

3.5.1  RouterA的配置

# 配置以太网口的IP地址

<RouterA>system-view

[RouterA]interface GigabitEthernet 0/1 

[RouterA-GigabitEthernet0/1]ip address 200.1.1.1 255.255.255.0

[RouterA-GigabitEthernet0/1]quit

# 创建RIP动态路由

[RouterA]rip 1

[RouterA-rip-1]version 2

[RouterA-rip-1]network 200.1.1.0

3.5.2  RouterB的配置

# 定义访问控制列表

<RouterB>system-view

[RouterB]acl number 3009

[RouterB-acl-adv-3009]rule 0 permit ip source 200.1.1.0 0.0.0.255

[RouterB-acl-adv-3009]quit

# 创建虚接口VT87,并配置其IP地址

[RouterB]interface Virtual-Template 87

[RouterB-Virtual-Template87]ip address 1.1.1.1 255.255.255.0 

[RouterB-Virtual-Template87]quit

# 配置串口S8/7,使其MP捆绑到虚接口VT87

[RouterB]interface Serial 8/7

[RouterB-Serial8/7]ppp mp Virtual-Template 87

[RouterB-Serial8/7]quit

# 定义1号节点,使匹配ACL 3009的任何IP报文被发往接口VT87,并配置与track1的联动配置

[RouterB]policy-based-route test permit node 1

[RouterB-pbr-test-1]if-match acl 3009

[RouterB-pbr-test-1]apply output-interface Virtual-Template87 track 1

[RouterB-pbr-test-1]quit

# 创建ICMP类型的NQA测试组(管理员为admin,操作标签为 1)并配置相关可选测试参数

[RouterB]nqa entry admin 1

[RouterB-nqa-admin-1]type icmp-echo

[RouterB-nqa-admin-1-icmp-echo]destination ip 1.1.1.2

[RouterB-nqa-admin-1-icmp-echo]frequency 5000

[RouterB-nqa-admin-1-icmp-echo]source ip 1.1.1.1

# 配置Reaction监测项1(失败1次触发联动)

[RouterB-nqa-admin-1-icmp-echo]reaction 1 checked-element probe-fail threshold-type consecutive 1 action-type trigger-only 

[RouterB-nqa-admin-1-icmp-echo]quit 

# 配置以太口GigabitEthernet0/1IP地址,在GigabitEthernet0/1接口上应用策略路由test

[RouterB]interface GigabitEthernet 0/1

[RouterB-GigabitEthernet0/1]ip address 200.1.1.2 255.255.255.0

[RouterB-GigabitEthernet0/1]ip policy-based-route test

[RouterB-GigabitEthernet0/1]quit

# 配置Track1,关联NQA测试组(管理员为admin,操作标签为 1)的Reaction监测项1

[RouterB]track 1 nqa entry admin 1 reaction 1

# 创建RIP动态路由

[RouterB]rip 1

[RouterB-rip-1]version 2

[RouterB-rip-1]network 200.1.1.0 

[RouterB-rip-1]network 1.1.1.0 

3.5.3  RouterC的配置

# 创建虚接口VT87,并配置其IP地址

<RouterC>system-view

[RouterC]interface Virtual-Template 87  

[RouterC-Virtual-Template87]ip address 1.1.1.2 255.255.255.0

[RouterC-Virtual-Template87]quit

# 配置串口S8/7,使其MP捆绑到虚接口VT87

[RouterC]interface Serial 8/7 

[RouterC-Serial8/7]ppp mp Virtual-Template 87

[RouterC-Serial8/7]quit  

# 创建RIP动态路由

[RouterC]rip 1

[RouterC-rip-1]version 2

[RouterC-rip-1]network 1.1.1.0

3.6  验证结果

(1)     启动ICMP测试操作

[RouterB]nqa schedule admin 1 start-time now lifetime forever  

(2)     在RouterB显示ICMP  NQA测试成功的结果,NQA将探测结果通知给TRACK模块,则对应Track项的状态为positive,就表示策略路由指定的出接口有效,可以指导转发

 [RouterB]display nqa result admin 1

  NQA entry(admin admin, tag 1) test results:

    Destination IP address: 1.1.1.2

      Send operation times: 1              Receive response times: 1

      Min/Max/Average round trip time: 38/38/38

      Square-Sum of round trip time: 1444

      Last succeeded probe time: 2011-09-28 15:11:57.1

    Extend results:

      Packet lost in test: 0%

      Failures due to timeout: 0

      Failures due to disconnect: 0

      Failures due to no connection: 0

      Failures due to sequence error: 0

      Failures due to internal error: 0

      Failures due to other errors: 0      

[RouterB]display track 1

Track ID: 1

  Status: Positive

  Duration: 0 days 0 hours 4 minutes 50 seconds

  Notification delay: Positive 0, Negative 0 (in seconds)

  Reference object:

    NQA entry: admin 1

    Reaction: 1 

(3)     在RouterA发5个ping包到1.1.1.2,查看RouterB的策略路由的统计信息,统计成功转发了5个数据包

<RouterB>dispaly ip policy-based-route statistics interface GigabitEthernet 0/1

 Interface GigabitEthernet0/1 policy based routing statistics information:

 policy-based-route: test

    permit node 1

       apply output-interface Virtual-Template87 track 1

          Denied: 0,

          Forwarded: 5

 Total denied: 0, forwarded: 5 

(4)     断开RouterB与RouterC之间的连接线缆,在RouterB显示ICMP NQA测试不成功的结果,NQA将探测结果通知给TRACK模块,则对应Track项的状态为Negative,就表示策略路由指定的出接口无效,转发时忽略该配置项

 <RouterB>display nqa result admin 1

  NQA entry(admin admin, tag 1) test results:

    Destination IP address: 1.1.1.2

      Send operation times: 1              Receive response times: 0

      Min/Max/Average round trip time: 0/0/0

      Square-Sum of round trip time: 0

      Last succeeded probe time: 0-00-00 00:00:00.0

    Extend results:

      Packet lost in test: 100%

      Failures due to timeout: 1

      Failures due to disconnect: 0

      Failures due to no connection: 0

      Failures due to sequence error: 0

      Failures due to internal error: 0

      Failures due to other errors: 0

<RouterB>dis track 1

Track ID: 1

  Status: Negative

  Duration: 0 days 0 hours 4 minutes 50 seconds

  Notification delay: Positive 0, Negative 0 (in seconds)

  Reference object:

    NQA entry: admin 1

Reaction: 1  

(5)     在RouterA发5个ping包到1.1.1.2,查看RouterB的策略路由的统计信息,统计显示忽略了这5个数据包,这些数据包无法通过此策略路由进行转发,需按正常转发流程处理。

<RouterB>dispaly ip policy-based-route statistics interface GigabitEthernet 0/1

 Interface GigabitEthernet0/1 policy based routing statistics information:

 policy-based-route: test

    permit node 1

       apply output-interface Virtual-Template87 track 1

          Denied: 5,

          Forwarded: 0

 Total denied: 5, forwarded: 0
