场景描述: 一台华为AR系列路由器(图中R1),一台H3C MSR系列路由器,
一台H3C S5500 核心交换机.
AR路由器接入WAN1和WAN2两条线路,H3C路由器接入WAN3线路无线网络专用.
内网使用172.16.x.x/24 ; wifi 使用172.16.100.0/23
大致拓扑如下:
要求:
1. Wifi流量到核心后,经过策略路由调度到Router2出口,且Wifi 能够和内部有线网络实现互通.
2. Wifi下载单IP限速3Mbps
3. Wifi专用线路出口拥塞后,在核心调度流量到Router2的WAN2出口
具体实现:
1. 核心策略路由:
#acl部分 acl number 3000 rule 0 permit ip source 172.16.100.0 0.0.1.255 destination 172.16.0.0 0.0.255.255 acl number 3001 rule 0 permit ip source 172.16.100.0 0.0.1.255 #Traffic分流 traffic classifier wifi01 operator and if-match acl 3000traffic classifier wifi02 operator and if-match acl 3001traffic behavior wifi01 filter permittraffic behavior wifi02 redirect next-hop 172.16.253.2 fail-action forward#定义Qos策略qos policy wifi classifier wifi01 behavior wifi01 classifier wifi02 behavior wifi02#应用Qos策略qos vlan-policy wifi vlan 100 inbound
2. Wifi限速
登录Router2:
qos carl 1 destination-ip-address subnet 172.16.100.0 23 per-address#WAN3接入口interface GigabitEthernet0/0 qos car inbound carl 1 cir 3000 cbs 25000 ebs 0 green pass red
3. 主路由流量调度
#核心修改策略路由acl number 3000rule 0 permit ip source 172.16.100.0 0.0.1.255 destination 172.16.0.0 0.0.255.255 #acl中将Wifi网段适当调小,通过掩码控制acl number 3002 description wifi-temp01 rule 0 permit ip source 172.16.100.0 0.0.0.255 traffic classifier wifi01 operator and if-match acl 3000traffic classifier wifi-temp operator and if-match acl 3002 traffic behavior wifi01 filter permittraffic behavior wifi-temp redirect next-hop 172.16.253.2 fail-action forward #新的Qos策略qos policy wifi-temp classifier wifi01 behavior wifi01 classifier wifi-temp behavior wifi-temp#应用新的Qos策略qos vlan-policy wifi-temp vlan 100 inbound#修改完核心策略路由,就可以将ACL中指定的wifi流量指定到Router1了, 但是Router1缺省出口路由为WAN1,而我们需要将流量导向到出口WAN2#acl定义acl number 2055 rule 0 permit source 172.16.100.0 0.0.1.255#定义流类和行为traffic classifier 1 operator or if-match acl 2055traffic behavior 1 redirect ip-nexthop x.x.x.x(WAN2出口下一跳地址)#定义流策略traffic policy 1 classifier 1 behavior 1#应用流策略#进入路由器内网口interface GigabitEthernet 0/0/2traffic-policy 1 inbound
这样就可以根据各个出口拥塞情况随意的进行流量调度了.
