Backbone-to-edge routing with Virtual Fabrics

Backbone-to-edge routing is not supported in the base switch, unless you use a legacy FC router. A
legacy FC router is an FC router configured on a Brocade 7500 switch or an FR4-18i blade.
Base switches can participate in a backbone fabric with legacy FC routers. You cannot connect
devices to the base switch because the base switch does not allow F_Ports. You can, however,
connect devices to the legacy FC router, thus enabling backbone-to-edge routing.
If you connect a legacy FC router to a base switch, you must set the backbone FID of the FC router
to be the same as that of the base switch.

switch. This FC router can have devices connected to it, and so you can have backbone-to-edge
routing through this FC router. In this figure, Host A in the backbone fabric can communicate with
device B in the edge fabric with FID 20; Host A cannot communicate with device C, however,
because the base switches do not support backbone-to-edge routing.
