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.

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

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!
