网通路由器电信、网通双线路智能切换配置指导

在很多地区网吧用户同时川请了中国电信和中国网通两条宽带接入线路如果此时双线路采用常规的“负载均衡”方式就会发生访问网通站点走电信线路访问电信站点走网通线路的悄况,山于当前网通和电信两个运营商Z间存在着互联互通速度慢的问题造成速度瓶颈。如何实现“访问网通站点走网通线路访问电信站点走电信线路”呢在华为AR系列路由器上可以通过配置策略路由的方式满足以上需要。

一。配置访问控制列表定义访问目的地址为网通的地址段

进入系统视图创建ACL3100

<Quidway>systcm

System View:return to User View with Ctrl+Z.

IQuidwayJacI num 3100

|Quidway-acl-adv-3100]

可以直接复制粘贴如下规则rule 0 permit ip destination 60.0.0.00.7.255.255rule 1 permit ip destination 60.0.0.00.8.255.255rule 2 permit ip destination 60.0.0.00.9.255.255rule 3 permit ip destination 60.0.0.00.10.255.255rule 4 permit ip destination 60.0.0.00.11.255.255rule 5 permit ip destination 60.8.0.00.3.255.255rule 6 permit ip destination 60.12.0.00.0.255.255rule 7 permit ip destination 60.13.0.00.0.63.255rule 8 permit ip destination 60.13」 2&00.0.127.255rule 9 permit ip destination 60.16.0.00.15.255.255rule 10 permit ip destination 60.20&0.00.7.255.255rule 11 permit ip destination 60.216.0.00.1.255.255rule 12 permit ip destination 60.220.0.00.3.255.255rule 13 permit ip destination 61.48.0.00.3.255.255rule 14 permit ip destination 61.52.0.00.1.255.255rule 15 permit ip destination 61.54.0.00.0.255.255rule 16 permit ip destination 61.55.0.00.0.255.255rule 17 permit ip destination 61.133.0.00.0.127.255rule 18 permit ip destination 61.134.64.00.0.63.255rule 19 permit ip destination 61.134.128.0( ) ・ ( )」 27.255rule 20 permit ip destination 61.135.0.00.0.255.255rule 21 permit ip destination 61.136.0.00.0.255.255rule 22 permit ip destination 61.13&0.00.0.127.255rule 23 permit ip destination 61.139.128.00.0.63.255rule 24 permit ip destination 61.148.0.00.0.255.255rule 25 permit ip destination 61.149.0.00.0.255.255rule 26 permit ip destination 61.156.0.00.0.255.255rule 27 permit ip destination 61.158.0.00.0.255.255rule 28 permit ip destination 61.159.0.00.0.63.255rule 29 permit ip destination 61.161.0.()0.0.63.255rule 30 permit ip destination 61」 61」 28.00.0」 27.255rule 31 permit ip destination 61.162.0.00.0.255.255

注以上规则已经包含大部分网通地址段如冇更新可以动态添加。

二。定义策略路由指定访问网通地址段的数据报文下一跳为网通网关

|QuidwayJroute-policy auto permit node 1

%New sequence of this list

[Quidway-routc-policy]if-match acl 3100

[Quidway-route-policy]apply ip-address next-hop 10.1.1.2

[Quidway-route-policyjdis this

#route-policy auto permit node 1if-match acl 3100apply ip-address next-hop 10.1.1.2

#return

[Quidway-route-po licy]

注上面配置中以地址10.1.1.2为例作为网通网关地址应用中可根据实际需婆修改。

三。在连接局域网接口下应用此策略路由

[Quidway]int e3/()

[Quidway-Ethcrnct3/0]dis this

#interface Elhernet3/0ip address 192.168.1.1255.255.255.0

#return

[Quidway-Ethernet3/0Jip policy route-policy auto

|Quidway-Ethernet3/0]dis this

#intcrfacc Ethcrnct3/0ip address 192.168.1.1255.255.255.0ip policy route-policy auto

#return

[Quidway-Ethcrnct3/0]

四。配置默认路由器经过电信网关ip route-static 0.0.0.00.0.0.020.1.1.2 preference 60

注:上面配置中以地址20.1J.2为例作为电信网关地址,应用中可根据实际需要修改。

经过如上三个配置步骤后路山器便能口动区分网通流量和电信流量使访问网通站点走网通线路访问电信站点走电信线路。并且当网通线路出问题后所冇流量都会自动切换到电信线路上使用户能够不间断访问网络。
