FC-FC routing and Virtual Fabrics
24
• Backbone-to-edge routing is not supported in the base switch. Refer to “Backbone-to-edge
routing with Virtual Fabrics” on page 503 for information about how to configure legacy FC
routers to allow backbone-to-edge routing with Virtual Fabrics.
• All FCR commands can be executed only in the base switch context.
• The fcrConfigure command is not allowed when Virtual Fabrics is enabled. Instead, use the
lsCfg command to configure the FID.
• Although the Brocade 6510 supports up to four logical switches, if you are using FC-FC routing,
the Brocade 6510 can have a maximum of only three logical switches.
Logical switch configuration for FC routing
Figure 80 shows an example of two chassis partitioned into logical switches. This configuration
allows the device in Fabric 128 to communicate with the device in Fabric 15 without merging the
fabrics. Note the following:
• The base switch in Physical chassis 1 serves as an FC router and contains EX_Ports that
connect to logical switches in the two edge fabrics, Fabric 128 and Fabric 15.
• The other logical switches in Fabric 128 and Fabric 15 must be connected with physical ISLs,
and do not use the XISL connection in the base fabric.
• The logical switches in Fabric 1 are configured to allow XISL use. You cannot connect an
EX_Port to these logical switches, so the device in Fabric 1 cannot communicate with the other
two devices.
FIGURE 80 EX_Ports in a base switch
Figure 81 shows a logical representation of the physical chassis and devices in Figure 80. As
shown in Figure 81, Fabric 128 and Fabric 15 are edge fabrics connected to a backbone fabric.
Fabric 1 is not connected to the backbone, so the device in Fabric 1 cannot communicate with any
of the devices in the other fabrics.
