how about the Route Setup NCE, since that connection will likely be
active between any pair of adjacent HPR nodes over any TG?

That would be fair, also.

There is a certain logic to that.  In that case you would need a bit in the
CV 61 SF 81 to explicitly suppress establishment of the LLC connection.

Would you then use the ALIVE timer and the subsequent SHORT_REQ timer error
recovery to detect the loss of the underlying link, and then use failure of
the Route Setup RTP connection itself as the trigger to declare the
underlying link dead?
