2 条 ADSL 线路接入 Cisco 2621XM 时上传/下载速度较慢

抱歉，我之前没有访问过此网站，所以如果不是正确的部分或论坛，我深感抱歉。

有用户抱怨网站的互联网连接速度非常慢，我向 ISP 核实后，他们说线路测试速度为 8mb。

我们有 2 条 BT 线路，上面有我们的 ISP 宽带。这两条线路都接入 Cisco 2600 系列路由器，然后路由器上有一个 PIX 防火墙。连接成功，只是速度很慢，无法下载任何内容。

配置如下：

现在我的知识非常有限，但 ISP 说过，虽然线路绑定了，但每条线路都需要单独的登录，因为他们最近更改了 L2TP 路由器，这强制使用单独的登录 - 当配置线路时，我们获得了两个登录名。

所以，我的问题是，为了使它正常工作，我需要对配置进行哪些更改？在他们改变之前一切都很好，而且我确实有另一个登录名 :-

01270 111111 -[电子邮件保护]
01270 222222 -[电子邮件保护]

IP 地址是否dialer1需要相同，dialer0因为问题只是身份验证？

ip route 0.0.0.0 0.0.0.0 Dialer0由于我已经创建了另一个拨号器界面，我是否需要进行更改？

当前配置如下：

抱歉问题太长，感谢您花时间阅读。如有任何我可以提供的信息，请告知我。

答案1

我认为您需要添加另一个像这样的拨号界面：

interface Dialer1
 ip address x.x.x.x 255.255.255.248
 encapsulation ppp
 dialer pool 2
 dialer-group 2
 ppp authentication chap callin
 ppp chap hostname [email protected]
 ppp chap password 7 xxxxx
 ppp multilink
!

然后，您将新的拨号池用于第二个 ATM 接口。

interface ATM0/1
 description 01270 222222
 no ip address
 no atm ilmi-keepalive
 pvc 0/38 
  encapsulation aal5mux ppp dialer
  dialer pool-member 2
 !
 dsl operating-mode auto
!

根据需要修改并填写。你可能需要看一下 cisco ios 文档：http://www.cisco.com/en/US/docs/ios/12_0/dial/configuration/guide/dcdbakdp.html#wp3753
