PPP Multilink framing errors

[bill.brune]

2811 router on each end. Two P2P t-1's. Either span performs perfectly within the bundle. However add both at once and framing errors start to appear on the multilink interface only. Multilink reliability falls back to 50%. Every inbound packet shows a framing error. This occurs on both routers. I would appreciate someone with more multilink experience to take a look at the attached configs.

Thanks

Hi,

you must be getting slips or framing errorn, check "show controllers t1.

Please configure external clock on both controllers as well on the remote side.

Also configure network-clock-participate wic X

and network-clock-select 1 T1 X/Y.

Hope this helps, please rate post if it does!
