Guidelines for setting up Fibre Channel routing
18
Figure 260 on page 671 shows a metaSAN with a backbone fabric and three edge fabrics. The
backbone consists of one 4 Gbps Router, Extension Switch connecting hosts in Edge fabrics 1 and
3 with storage in Edge fabric 2 and the backbone fabric. LSANs provide device sharing between the
following pairs of fabrics:
•
The backbone fabric and Edge fabric 1
•
Edge fabric 1 and Edge fabric 2
•
Edge fabric 2 and Edge fabric 3

Guidelines for setting up Fibre Channel routing
The following are some general guidelines for setting up Fibre Channel 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.
