Description

Use this command to display routes through the MP Router backbone fabric to accessible destination edge

fabrics.

An MP Router backbone fabric is the fabric that contains the E/F_Ports of this MP Router and routes

interfabric traffic between edge fabrics, creating a meta-SAN.

There are MP Router NR_Ports that reside on the backbone fabric. MP Router NR_Ports send/receive

interfabric traffic. 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 this XPath OS release does not support cascaded backbone/intermediate fabrics, an NR_Port

provides a path to a single fabric with a single link cost. Multiple NR_Ports can provide paths to the same

destination fabric.

The message No routes found is displayed if there is no route information available at this MP Router.

There will be no route information available if there are no EX_Ports configured at this MP Router.

Each line of output displays the following information:

Destination Fabric

The destination fabric.

NR_Port PID The port ID of the NR_Port. This 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.

FCRP Cost The FCRP cost (for routing decisions) for this NR_Port. In this

release, the FCRP cost is always the same (1000) for all

NR_Ports.

WWN of the

Principal Switch in

the Dest Fabric

The world wide name of the principal switch in the destination

fabric specified by the Destination Fabric ID column. This

is useful for correlating the fabric ID listed in the Destination

Fabric ID column with the actual fabric.
