举例:配置智能策略路由
组网需求
如图13-4所示,CPE1和CPE2之间已部署SD-WAN EVPN传输网络MPLS和Internet,MPLS专线作为主用链路,Internet链路作为备用链路。CPE之间的业务要求链路时延不超过100ms,抖动时间不超过50ms,丢包率不超过5‰,且综合度量指标不超过200。CPE1和Site连接的物理接口Interface1上使能应用识别功能,并绑定站点中的VPN实例。
配置思路
配置区分业务流的应用组。
新建业务模板并绑定应用组。
新建策略模板并绑定业务模板。
配置链路切换指标。
配置策略关联链路。
配置策略应用到站点中的VPN实例。
操作步骤
配置区分业务流的应用组。
<HUAWEI> system-view[HUAWEI] sysname CPE1[CPE1] interface 10ge 0/0/1[CPE1-10GE0/0/1] ip binding vpn-instance vpn1[CPE1-10GE0/0/1] ip address 10.1.1.1 24[CPE1-10GE0/0/1] quit[CPE1] interface 10ge 0/0/1[CPE1--10GE0/0/1] sa enable[CPE1--10GE0/0/1] quit[CPE1] application-group name chat[CPE1-application-group-chat] add application welink[CPE1-application-group-chat] quit
新建业务模板并绑定应用组。
[CPE1] smart-policy-route[CPE1-smart-policy-route] service-map map1[CPE1-smart-policy-route-service-map-smap] match application-group chat[CPE1-smart-policy-route-service-map-smap] quit
配置策略模板。
[CPE1-smart-policy-route] spr-policy node 1[CPE1-smart-policy-route-spr-policy-node-1] binding service-map map1
配置链路切换指标。
[CPE1-smart-policy-route-spr-policy-node-1] delay threshold 100[CPE1-smart-policy-route-spr-policy-node-1] jitter threshold 50[CPE1-smart-policy-route-spr-policy-node-1] loss threshold 5[CPE1-smart-policy-route-spr-policy-node-1] cmi threshold 200
配置策略关联链路。
[CPE1-smart-policy-route-spr-policy-node-1] link transport-network mpls[CPE1-smart-policy-route-spr-policy-node-1-link-tn-mpls] link-role master[CPE1-smart-policy-route-spr-policy-node-1-link-tn-mpls] link-priority 1[CPE1-smart-policy-route-spr-policy-node-1-link-tn-mpls] quit[CPE1-smart-policy-route-spr-policy-node-1] link transport-network internet[CPE1-smart-policy-route-spr-policy-node-1-link-tn-internet] link-role backup[CPE1-smart-policy-route-spr-policy-node-1-link-tn-internet] link-priority 1[CPE1-smart-policy-route-spr-policy-node-1-link-tn-internet] quit
策略模板与站点中的VPN实例绑定。
[CPE1-smart-policy-route-spr-policy-node-1] apply-to vpn-instance vpn1
检查配置结果
在CPE1上执行命令display smart-policy-route spr-policy all查看策略模板配置信息。
<CPE1> display smart-policy-route spr-policy all-------------------------------------------------------------------------------- SPR-policy Info: PolicyNode : 1 PolicyPriority : 1 SwitchBack : enable DefaultAction : forward TimeRange : - TimeRangeStatus : - Threshold Info: Loss : 5 Delay : 100 Jitter : 50 CMI : 200 Service Map Info: ServiceMapID : 1 ServiceMapName : map1 Match content: MatchType : OnlyAppGroup AppGroup : chat Link Info: Master TransportNetwork(1) : TNId TNName Priority SRv6Path 1 MPLS 1 Backup TransportNetwork(1) : TNId TNName Priority SRv6Path 2 Internet 1 -------------------------------------------------------------------------------- Number of SPR-policy: 1 --------------------------------------------------------------------------------
在CPE1上执行命令display smart-policy-route spr-instance all查看生成的智能策略路由实例以及最终选路结果。
