Summary: What is going on here ?
Keywords: IGS slow

I have installed an IGS to IGS link over a 64Kbps line.

The router at my end becomes very very slow, every couple of days or so.
On inspection of interfaces, buffers, cpu and protocol interfaces
I can't see anything that is startling or anything that would slow it
down! 50% of pings to the IGS over ethernet would be lost.

I have been reloading it just to get the users going again,
but today I found that a "clear int ethernet 0" command
fixes the problem.

Is this a known problem?

Strange that a manual interface reset is required!

The router version is:
