[HECnet] FDDI advice

[Peter Lothberg]

FDDI/CDDI is a dual ring token ring bus, with 4470 MTU byte packets,
it has 802.-- frames. DEC had a mode where you turned the token off
and used it for ptp full duplex.
I didn't know about the ptp thing. That's nifty.

A cisco FDDI-PA can talk both in a 7500 or old 7200 (the VXR don't
support the FDDI cards but the VIP does ).

I don't think there ever was a CDDI PA..

Sol.Stupi.SE that has a CDDI interface has a media converter from
copper to fiber and then it plus in to a old 7200...
