I have an Internet Router with 4 seriel Interface, each of them connected to an E1. The first 2 ports have been Multilinked and is working fine.

However when I tried to Multilink the other 2 lines as a second Multilink, I could not do it. The ISP says they gave the 3rd and 4th line on 2 different cards at their end. Is it necessary for the 2 ports to be multilinked to be on the same card or is it enough that they be in the same router.

I have this problem too.

What is the router at your end and at the ISP's end. It is not rnough to have the 2 ports multilinked on the same router. There are some restrictions on the IOS, that your ports have to be on the same card.

Please see a link below for the same restrictions on MLPPP.

Can you post out the show version and show run output of your router ?
