We have set up a link beetween an AGS/2 and IGS/R. This was suppost
to use a 2Mb/s modem connection. But to make it work, the speed of the
link had to set down to 512Kb/s.
At 1 Mb/s IP- DECnet- and AppleTalk-routing worked, but to get bridging
work we had go down to 512.

Before the ciscos was installed, the link was used by 2 Vitalinks.
They reported no errors on the link at 2 Mb/s.

So the question is then: 
 Is it the AGS/2 or IGS/R that can not handle 2 Mb/s with IP, DECnet, AT 
 and bridging.


This is the config:
