Multilink Errors and Reliability

Unanswered Question
May 20th, 2009

I have 3 Serial interfaces setup in a multilink configuration. The Multilink interface receive a packet error for almost every input packet. The CRC error counts are almost the same count also. I've checked each individual Serial interface and they show NO errors.

In addition, my Multilink interface availability is constantly 128/255. I will post run-configs and interface status. Thanks in advance for any help.

I have this problem too.

Unfortunately no. The router is an old 3660 and would need a memory upgrade first.
