Hi Scott,
But it suppose the connection should not work.
In the setting, I try both end use the command "frame-relay ip tcp
header-compression" on the interface. Then one end I just enter the
frame-relay map command and make it inherit the compression, and at the
other end (RouterA), I use the command frame-relay map with nocompress to
disable the compression. However, it seems that the nocompress is entered
dynamically by the end of RouterB, and the PVC is negotiated to uncompress
and the connection works fine.
Best Regards,
William Chen
