Fcrrouteshow - Brocade Communications Systems Brocade 8/12c Command Reference Manual

fcrRouteShow

Displays FC Router route information.
SYNOPSIS
fcrrouteshow
DESCRIPTION
Use this command to display routes through the FC Router backbone fabric to accessible destination
fabrics. An FC Router backbone fabric is the fabric that contains the E_Ports of this platform and routes
inter-fabric traffic between imported fabrics, creating a meta-SAN.
There are FC Router ports that reside on the backbone fabric. These ports are known as NR_Ports.
NR_Ports send and receive inter-fabric traffic. For the AP7420, there is a one-to-one relationship
between an NR_Port on a backbone fabric and an EX_Port. NR_Port technology enables EX_Ports to
exchange traffic across an intermediate fabric. NR_Ports are addressable entities on the backbone fabric
and have port IDs relevant to the backbone fabric.
Because cascaded backbone/intermediate fabrics are currently not supported, an NR_Port provides a
path to a single fabric with a single FC Router protocol cost. Multiple NR_Ports can provide paths to the
same destination fabric.
"No routes found" is displayed if there is no route information available at this FC Router. There is no
route information available if no EX_Ports are configured at this FC Router.
The output includes:
Destination Fabric ID
NR_Port PID
FCRP Cost
WWN of the Principal Switch in the Dest. Fabric
NOTES
The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in
place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for

The destination fabric.
The port ID of the NR_Port. The port ID is relevant only on the backbone fabric.
This NR_Port has a route to the destination fabric identified by the "Destination
Fabric ID" column.
The FC Router protocol cost (for routing decisions) for this NR_Port. The FCRP
cost is the same (1000) for all NR_Ports.
The world wide name of the principal switch in the destination fabric.
