hi,
I configured 2 routers with the following multilink configuration:
Router # 1
interface Multilink1

I also set any static route that was pointing to a serial interface to point to multilink1.
Any suggestions?

hi,
what is the exact problem is???
packet dropping or multilink connection is not establishing.

I am able to ping from one router to the other router (FastEthernet interfaces) however I can not go past that (reach servers, etc...) on the other side.

hi,
if you are not able to ping further then it will be the issue of the internal network.

I agree with Davang that you have provided some details on what you have done but not nearly enough detail about what the problem is. In addition to some detail of what is not working it would be helpful to have the output of show interface and of show ppp multilink.
Also I notice that both routers have both an IP address configured on the multilink interface and ip unnumbered on the interface. They should not both be on the same interface. I would suggest that you remove the ip unnumbered from both interfaces.
EDIT: it looks while I was writing my post that Nasir has provided additional information. From his response it seems that he can ping from one router to the other, so the link appears to be working satisfactorily. If he can not ping further than the other router it sounds like a routing issue.
First I would suggest post the output of show ip route from a router and see if routes from the other router have been learned. I am guessing that they have not.
If routes from the other router have not been learned then we need to investigate why. My first guess is that it may be an authentication problem. So I would suggest removing authentication from the config and see if things work better.
If that is not the problem then perhaps Nasir can provide some additional details.

hi,
i am still confusing as you have confiugre interface multink with command ip address as well as ip unnumbered fastethernet
i think it will be much better to use the multilink virtual-templet.
rate the post if it helps
