There is one exception to this in reasonably common inter-provider
practice. At a multiprovider exchange point, you may have several
providers announcing a MED to one another, following a convention
that sets the MED to an estimated delay. In this case, you'd want to
be sure to code always-compare-med and deterministic-med.
See Avi Freedman's presentation at the NANOG December meeting in
1999: http://www.nanog.org/mtg-9901/ppt/bgp102/index.htm for the
PowerPoint and http://www.nanog.org/mtg-9901/ppt/bgp102/index.htm for
HTML. I just noticed my "BGP 101", which immediately preceded his
"BGP 102", is missing from the page -- I thought it was there,
although I have some other tutorials on BGP at NANOG such as
http://www.nanog.org/mtg-0102/exterior.html (PowerPoint, HTML, and
RealVideo)
I would be extremely surprised to see this usage in CCIE R&S.
POSSIBLY C&S. It is in several Cisco ISP workshops.
