PPP Multilink from two ISP's - One link goes Offline and doesn't come

[dwehalle]

Hi,

The problem is with two PPP Multilinks configured from two different ISP's. Both of them work fine for a day or two and then if one link fails and come back Online again, the routers won't pick up the line protocol as "up".

It says " interface status "up" and Line protocol "down" on one link (even if the physical link is Online). The other link from the other ISP remains "up" and Online.

Even if I reset the physical interface it won't show status "up", while the actual physical link is back Online. Can someone help me to resolve this Issue.

Thanks and Regards
