Guidelines for setting up FC-FC routing
The following are some general guidelines for setting up FC-FC routing:
Ensure that the backbone fabric ID of the FC router is the same as that of other FC routers in
the backbone fabric.
On the FC router, ensure that the ports to be configured as EX_Ports are either disabled or not
connected.
When configuring EX_Ports, supply a fabric ID for the fabric to which the port will be connected.
You can choose any unique fabric ID as long as it is consistent for all EX_Ports that connect to
the same edge fabric.
For Virtual Fabric (VF)-enabled fabrics, only the base switch can be configured as the FC router;
for example, EX_Ports can be configured only on a base switch for a VF-enabled switch.
Connecting edge fabrics to a backbone fabric
The following procedure explains how to set up FC-FC routing on two edge fabrics connected
through an FC router using E_Ports and EX_Ports.
ATTENTION
Be sure that you do not physically connect a port to the remote fabric before configuring it as an
EX_Port; otherwise, the two fabrics merge and you lose the benefit of FC-FC routing.
