关于7206VXR路由器上如何防范BT

  首先路由器的IOS版本满足条件(12.2(5)T以上) 有几种方式: 1、 对于BT完全限制 ( 见下例policy-map XX的不同部分)(采用NBAR) 2、 对于BT的速率进行限制(见下例policy-map XX的不同部分)(采用NBAR) 3、 通过优先级队列完成 一、有地址转换的情况: ip nbar pdlm bootflash:bittorrent.pdlm (必须先启动) class-map match-all bt match protocol bittorrent ! ! policy-map bt1 (完全丢弃) class bt drop policy-map bt2 (速率限制) class bt police cir 50000 conform-action transmit exceed-action drop policy-map bt3 (速率限制) class bt police cir 300000 conform-action transmit exceed-action drop interface FastEthernet0/0 ip address 192.168.34.240 255.255.255.0 ip nat outside ip virtual-reassembly service-policy input bt3 (下载限制) service-policy output bt2 (上传限制) duplex full ! interface FastEthernet1/0 ip address 192.168.101.1 255.255.255.0 ip nat inside ip virtual-reassembly duplex full ! ip classless ip route 0.0.0.0 0.0.0.0 192.168.34.1 ! no ip http server ! ip nat pool pool1 192.168.34.240 192.168.34.240 netmask 255.255.255.0 ip nat inside source list 1 pool pool1 overload ! access-list 1 permit any 二、没有地址转换: ip nbar pdlm bootflash:/bittorrent.pdlm class-map match-all bt match protocol bittorrent ! ! policy-map bt2 class bt police cir 160000 conform-action transmit exceed-action drop policy-map bt3 class bt police cir 240000 bc 60000 pir 350000 conform-action transmit exceed-action drop policy-map bt1 class bt drop ! ! ! ! interface Loopback0 no ip address no ip route-cache ! interface FastEthernet0/0 ip address 192.168.101.1 255.255.255.0 duplex full ! interface FastEthernet1/0 ip address 192.168.102.254 255.255.255.0 service-policy input bt3 service-policy output bt2 ip route-cache policy duplex full ! ip classless ip route 0.0.0.0 0.0.0.0 192.168.102.1
