Jim,
You can answer these questions yourself with just a couple
routers. Configure a router to set the DE bit for ICMP traffic, ping
the remote router, and then check the "show frame pvc" command on the
remote router to see the number of frames that arrived with the DE bit
set.
As a side note, setting the DE bit yourself in the real world
isn't always a good practice.

Thanks Swaroop.
That's what I was thinking.
So, you agree with me that's there's no such thing in Frame Relay as a
"DON'T DISCARD" setting.
There's only a DISCARD ELIGIBLE setting.
And, therefore the only way to make some traffic NOT Discard Eligible is
to
make all other traffic Discard Eligible. You agree?
I have a couple other questions that maybe you could help me out with
regarding DE.
1) What's the difference, if any, between using the MQC to set the DE
bit
and using the frame relay de-group and de-list commands?
2) If I have a frame relay interface with sub-interfaces, if the DE is
applied at the physical level, will all the sub-interfaces inherit the
setting?
Thanks again. I appreciate the help. Tim
