A customer plans to have two risers and inter floor fiber he
is looking for an FDDI configuration.
There is a requirement for dedicated ethernet and FDDI ports
on each floor.
One suggested configuration is a single dual FDDI ring.
Is there a way of providing interconnected multiple FDDI
rings without using a GigaSwitch ?

No. The GigaSwitch is the only FDDI/FDDI bridge we have.
You can interconnect them all by just chaining the hubs:

Slight correction: Not that it's practical here, but you can also connect up to 3 FDDI rings together with the DECNIS bridge/router. Do you really need to keep 3 rings? If not, the suggestion in .-1 is fine. Also, there are several alternative "treeing" configurations you might consider. See the FDDI System Level Description for more info. -Mike P. | |||||

Thank you for the replies.
As I understand the only way our competitors can connect FDDI rings
is via a router, Again placing the Gigaswitch in a unique position.
Dual rings vs a tree configuration ----- I have seen some
tree configuations - the rules seen more complicated that using
a dual ring. What is the "religion" around tree'd FDDI's ?
