i have some problems with ppp multilink.

On an 2Mb/s (E1) link i see many lost fragments. When i disable ppp
multilink it works fine, but i must work with multilink (i have normaly
sgbp on the access-side). On the access-side works AS5400 (IOS 12.2(16)
a) at the remoteside C3640 (IOS 12.0(15) with other IOS (12.2(16) are no
changes). Has anybody hints for me?

here the config for the interface on the remote:

interface Serial0/0:15
description Eigene Rufnummer: 0815
ip unnumbered Loopback10
no ip directed-broadcast
encapsulation ppp
load-interval 30
no keepalive
dialer enable-timeout 2
dialer wait-for-carrier-time 5
dialer string 1
dialer string 2
dialer hold-queue 75
dialer load-threshold 80 either
dialer-group 1
isdn switch-type primary-net5
ppp authentication chap
ppp multilink
ppp timeout multilink link remove 20

at the access side are the same.

here the output from show pp multilink at the remoteside (the accessside
has no errors or lost fragments.
