We have some spoke sites connected to HUB location. All the sites are having 2 E1 links which are bundled via Multilink. The issue is when we pump traffic on it the CRC and errors on both the links at spoke site increases and when we unbundled the links it works fine. Also when we ping even with heavy size packet there is no drop, no crc and no errors increases. Also the provider as given the clean chit.
What could be the issue. I have attached the config file.
