FC-FC routing overview

- ICL ports on the core blades. EX-Port on ICL is supported only in DCX 8510-8 and DCX
8510-4 when all the port blades in the chassis belong to one of these blade types:
FC16-32, FC16-48, FC8-32E, FC8-48E).
NOTE
Device discovery will not occur properly with ICL EX-Port connected edge fabrics if the FC
Router has unsupported blades which are not mentioned above.
For the Brocade Backbone families, the backbones have a limit of 128 EX_Ports for each chassis.
Refer to the Network OS Administrator’s Guide for supported Network OS platforms.
Supported configurations for FC-FC routing
FC-FC routing supports the following configurations:
• FC router connected to a Fabric OS nonsecured edge fabric.
• FC router connected to a Fabric OS secured edge fabric.
• FC router connected to a Brocade Network OS edge fabric (Network OS v2.1.1 or later).
• FC router connected to an M-EOS Open Mode edge fabric.
• FC router connected to an M-EOS Fabric Mode edge fabric.
• FC router interoperating with legacy FC routers (Brocade 7500 switch).
In configurations with two backbone fabrics connected to the same edge fabric, routing is not
supported between edge fabrics that are not directly attached to the same backbone fabric.
Routing over multiple backbone fabrics is a multi-hop topology and is not allowed.
In an edge fabric that contains a mix of administrative domain (AD)-capable switches and switches
that are not aware of AD, the FC router must be connected directly to an AD-capable switch. For
more information, refer to “Use of Admin Domains with LSAN zones and FC-FC routing” on
page 620.
VEX edge to VEX edge device sharing is not supported.
Network OS connectivity limitations
You should be aware of the following configuration limitations for Network OS connectivity:
• All of the platforms listed in “Supported platforms for FC-FC routing” on page 594 support
FC-FC routing to a Brocade Network OS fabric, except for the Brocade Encryption Switch.
• VEX_Ports do not support Network OS connectivity.
• FCoE devices connected to an FCOE10-24 blade cannot communicate with FCoE devices in the
Network OS fabric.
• If Admin Domains are enabled, connectivity between the Fabric OS fabric and a Brocade
Network OS fabric is not supported.
• Connectivity between a Brocade Network OS fabric and an M-EOS fabric is not supported.
