Hi
And thanks one and all for the help!
I feel a lot more confident in my understanding.
It has been my understanding that the sending host would always send any
retransmitts, with the exception of something like a X25 or LLC2 network in
between hosts. But I got to reading a bit more on RSRB an

I did read your statement correctly.
Which datalink protocols retransmit errored frames without the
knowledge of the host? Are there some that do it by default? Are there
some that don't do this by default but can be configured to do so?

Why not take a look at X.25 the protocol accounted for "missing frames".
I'm not sure about the specifics of what HDLC does if a CRC error occurs,
but I'd imagine it would re-transmit

What can be seen by my statement is that the host would re-transmit unless
there was a CRC problem on the serial link that the protocol corrected on
its own. Please read more carefully.

Lest we go through all of this again, a few weeks ago there was a great
thread on this very topic. The resolution was that in just about every
situation, it is the hosts that do the retransmitting, NOT the routers!
To find out why, go to the archives and search through the last three
months for

Hello,
Well, it depends what type of transmission problem occurs. If a
CRC failure occurs on the serial link depending upon the protocol being
used between devices then that data may or may not be re-transmitted.
However, if either error checking is not present, or the devices do not
