Hi Priscilla/All,
Thanx for the reply.all are absolutely right when keepalives are exchanged
they are not compressed.i would like to mention here only keepalives.I debug
the o/p
again ,even the cdp frames are compressed.
Like to share the Debug O/P with u all for dummy setup
nice job of examination and observation. thanks.
may I suggest that CDP packets, as with ftp, tftp, or any other data
packets, are payload to the HDLC frame.

Hi
Hi All,
I have question regarding HDLC,a silly question but still a doubt.See I have
HDLC connection back to back.on one interface I configure compression and
other interface on other router no compression.Now when I debug the my seq
and mine seen no.s are in sync I mean same they inncrease ,that
WAN compression usually compresses the data payload. The HDLC sequence
numbers are not in data packets; they are in keepalive packets. They are in
the control plane, not the user plane.
I can't say for sure, but my guess is that they are not compressed. If they
were, the interfaces wouldn't have

I can't say for sure,
HDLC sequences numbers aren't in data frames. They are in separate keepalive
frames. They aren't like TCP sequence numbers, which sequence the data. They
aren't in the header of the data frame. They are in separate frames in the
control plane.
Which, to make a long and winding story short,
6 matches
