Start up all netware AppleTalk FDDI devices before you start the cisco
routers.  Make sure all cisco routers are running 9.0(2) or later. Then
bring up the cisco routers on the FDDI ring. The cisco will go into
'pre-FDDITalk compatibility' if it hears any pre-9.0(2) cisco routers on
the ring. Once in 'pre-FDDItalk' mode, the cisco will not come back out
until the interface is restarted.

Admittedly, this is not a superior solution to this compatibilty
problem. The origin of this situation is that cisco provided AppleTalk
on FDDI before Apple had defined what AppleTalk on FDDI was going to
look like. So we have to be compatible with our installed base of
routers, yet implement the new FDDITalk specification to function with
other vendors (eg, Novell)

In the next major release, we plan to have a router be able to be
compatible with pre-9.0(2) routers and FDDItalk devices on the same
ring at the same time with no configuration flags.
