Multilink PPP problem on cisco 3745 router

Dear All,We had R1(cisco 3745) & R2(cisco 1721) routers with 2 64kbps Leased line between them.

On R1 this links are terminated as 2 diff 64 speed timeslots on Channeslised E1. On R2 these are physically seperate links with RAD modems.

This 2 links works fine when configured individually.

But when this links are added to multilink group they goes down.

I had checked the MPPP config at both ends its perfect.

R1 & R2 has many such multilinks which are working fine.

What could be the problem ?

If any one has some idea, please help !!!

Note:- If i replace R1 with cisco 2600 series router it works fine.


Re: Multilink PPP problem on cisco 3745 router

In the case of R1, try to set the speed setting. Because only thing I am suspecting with the configuration is with of channelized E1 according to your mail. I expect there is no problem with PPP multilink configuration.

Hope this link helps for multilink virtual template configuration...
