A question about two adsl card dial

I have a cisco 2811 device, include two adsl card.

Now, I need to configure two dialer interfaces and bundle to two atm sub interfaces.

Configuration file like that:

interface ATM0/0/0.3 point-to-point

ip load-sharing per-packet

ip route-cache cef

no ip mroute-cache

no ip directed-broadcast

no ip redirects

no ip proxy-arp

pvc vpn 0/50

inarp 1

no oam-pvc manage

no ilmi manage

pppoe-client dial-pool-number 3

interface Dialer3

ip address negotiated

ip route-cache cef

no ip mroute-cache

ip access-group <test> in

encapsulation ppp

load-interval 30

dialer pool 3

no ip directed-broadcast

no ip redirects

no ip proxy-arp

no cdp enable

keepalive 10

ppp authentication chap callin

ppp chap hostname cisco

ppp chap password cisco

another atm interface configure is the same with this.

two dialer interface use same username and password,so the radius server will distribute the same ip on it .

I want to know which IOS version can support this, and this configuration whether is right or not ?

Thank you very much.

Re: A question about two adsl card dial

Hello Zhang,

you should add PPP multilink to the picture to be able to use two links as a single PPP link.

something similar to:

http://www.cisco.com/en/US/docs/ios/12_2/dial/configuration/guide/dafppp.html#wp1032982

OR you can use two different dialers that will get two different ip addresses and you can then use two default static routes:

ip route 0.0.0.0 0.0.0.0 dialer1

ip route 0.0.0.0 0.0.0.0 dialer2

here the problem is the NAT part.

Hope to help

Re: A question about two adsl card dial

Hello,

If dont use ppp multilink.

Use two dialer interfaces, The two dialer interface's dialer username and password are the same. If radius server can distribute the same ip with same username and password, the two dialer can get same ip and turn to up ?

Thanks!
