MPLS QoS配置

MPLS QoS配置1.3.1 对同一VPN内的流进行QoS配置1. 组网需求如图1-1，网络描述如下：●CE 1和CE 2都属于VPN 1●PE 1与P之间的链路带宽为2M●P与PE 2之间的链路带宽为2M组网需求为对VPN 1中优先级不同的流给予不同的QoS保证。

配置可分为两个主要部分：首先在CE 1、PE 1、P、PE 2和CE 2进行MPLS VPN的配置：●PE 1、P、PE 2之间运行OSPF●PE与CE之间建立MP-EBGP邻居●PE与PE之间建立MP-IBGP邻居然后是在PE 1和P上进行MPLS QoS的配置：●在PE 1的入接口GigabitEthernet1/0/1上配置QoS策略，根据MPLS报文的DSCP属性，设置报文EXP域的值。

●在P设备上，根据MPLS报文的EXP域值区分流，配置基于流的队列CBQ：对于EXP为1的流保证10%的带宽；对于EXP为2的流保证20%的带宽；对于EXP为3的流保证30%的带宽；而对于EXP为4的流，保证40%的带宽并保证低时延。

MPLS VPN的配置请参考本手册“MPLS配置指导”中的“MPLS L3VPN”，下面只描述MPLS QoS部分的配置。

MPLS QoS主要完成以下功能：z根据需要选择在CE上或PE上对业务流进行分类，如可以将EXP值为2的流分为一类，EXP值为3的流分为一类，对分类后的流量可以进行流量监管、重新标记EXP等。

z PE在给报文加Label时，把IP报文携带的IP优先级标记映射到标签的EXP 域，这样原来由IP携带的服务类型信息，现在由标签携带。

z在P路由器和PE路由器之间，根据标签的EXP域，进行有差别的队列调度（如PQ、CQ、CBQ等），即把携带标签的业务流在一条LSP上进行有差别的QoS的传送。

VRP支持MPLS QoS。

说明：本章用户需要有MPLS相关知识背景。

如需了解MPLS基本概念以及相关配置，请参见《通用路由平台VRP MPLS分册》，本章仅涉及MPLS QoS的配置。

10.2 配置MPLS的流量监管10.2.1 建立配置任务1. 应用环境通过对进入MPLS网络的报文进行流量监管，可以限定报文的传送速率，避免网络拥塞的发生，并可以对报文重新标记优先级。

2. 前置任务在配置MPLS的流量监管之前，需完成以下任务：z配置MPLS基本能力z配置相关接口的物理参数z配置相关接口的链路属性z配置相关接口的IP地址z配置ACL或CARL3. 数据准备在配置MPLS的流量监管之前，需准备以下数据：序号数据1 ACL号、CARL号2 承诺信息速率、承诺突发尺寸、过度突发尺寸3 MPLS EXP值4 接口类型及编号4. 配置过程序号过程1 配置MPLS的流量监管10.2.2 配置MPLS的流量监管步骤操作命令1 进入系统视图system-view2 进入接口视图interface interface-type interface-number步骤操作命令3 配置MPLS流量监管qos car inbound { any | acl acl-index | carlcarl-index } cir cir cbs cbs ebs ebs green actionred action只能在PE的入接口上才可以设置MPLS报文的EXP域。

如果入接口的入方向为IP报文，输出接口的出方向封装为MPLS报文，则配置的流量监管策略生效。

标记MPLS报文的EXP域时，内外层标签都要设置，但不修改IP头部中的TOS域。

10.3 配置MPLS基于类的QoS10.3.1 建立配置任务1. 应用环境在MPLS网络中，若要通过MPLS EXP域来对MPLS报文分类并提供不同的服务，依据匹配的流量类别在MPLS中重新标记优先级后转发，需要配置MPLS的CBQoS。

2. 前置任务在配置MPLS的CBQoS之前，需完成以下任务：z配置MPLS的相关参数z配置接口的物理参数z配置接口的链路属性z配置接口的IP地址3. 数据准备在配置MPLS的CBQoS之前，需准备以下数据：序号数据1 EXP域的值2 CBQoS的类名3 CBQoS的行为名4. 配置过程序号过程1 定义匹配MPLS报文的EXP域的规则序号过程2 标记MPLS EXP域的值10.3.2 定义匹配MPLS报文的EXP域的规则步骤操作命令1 进入系统视图system-view2 进入类视图traffic classifier classifier-name [ operator{ and | or } ]3 定义匹配MPLS报文的EXP域的规则if-match [ not ] mpls-expmpls-experimental-value&<1-8>该配置只是定义了匹配类的规则，还需要确定对于该类报文采用的动作并与类进行关联，应用到接口。

关于动作与类的关联及应用到接口的配置，请参见“第5章基于类的QoS配置”。

10.3.3 标记MPLS EXP域的值步骤操作命令1 进入系统视图system-view2 进入行为视图traffic behavior behavior–name3 标记MPLS EXP域的值remark mpls-exp exp该配置只是对于已经定义的类重新标记MPLS EXP域的值，还需要与类进行关联，并应用到接口。

关于类与动作的关联及应用到接口的配置，请参见“第5章基于类的QoS配置”。

10.4 配置MPLS的队列管理10.4.1 建立配置任务1. 应用环境配置MPLS的队列管理，可以将超出带宽的报文根据报文的优先级进入相应的队列，之后再按照队列调度机制进行发送，避免报文的直接丢弃。

MPLS中可以配置PQ、CQ、WFQ、CBQ等。

说明：WFQ的配置请参见“第3章拥塞管理配置”，CBQ按照MPLS基于类的QoS方式进行配置。

2. 前置任务在配置MPLS的队列管理之前，需完成MPLS的基本能力的配置。

3. 数据准备在配置MPLS的队列管理之前，需准备以下数据：序号数据1 EXP域的值2 定制列表号、队列长度3 优先列表号4. 配置过程序号过程1 配置MPLS的定制列表2 配置MPLS的优先列表10.4.2 配置MPLS的定制列表步骤操作命令1 进入系统视图system-view2 配置MPLS的定制列表qos cql cql-index protocol mpls expmpls-experimental-value &<1-8>queuequeue-number3 进入接口视图interface interface-type interface-number4 应用CQ qos cq cql cql-index10.4.3 配置MPLS的优先列表步骤操作命令1 进入系统视图system-view步骤操作命令2 配置MPLS的优先列表qos pql pql-index protocol mpls expmpls-experimental-value&<1-8>queue{ top |middle | normal | bottom }3 进入接口视图interface interface-type interface-number4 应用PQ qos pq pql pql-index10.5 MPLS QoS配置举例1. 组网需求如图10-1所示，CE1和CE2都属于VPN1，PE1与P之间的链路带宽为155M，而P与PE2之间的链路带宽为2M，要求对VPN1中优先级不同的流给予不同的QoS保证。
