connect the logical switches with FID 1 and the logical switches with FID 15. The logical switches
with FID 8 are each connected to a non-Virtual Fabrics switch. The two logical switches and the
non-Virtual Fabrics switch are all in the same fabric, with FID 8.

The ISLs between the logical switches are dedicated ISLs because they carry traffic only for a single
logical fabric. In
cannot communicate with each other because they have no ISLs between them and they cannot
use the ISLs between the other logical switches.
NOTE
Only logical switches with the same FID can form a fabric. If you connect two logical switches with
different FIDs, the link between the switches segments.
