Configuring Fibre Channel Routing Services and
Protocols
Fabric Shortest Path First (FSPF) is the standard path selection protocol used by Fibre Channel fabrics.
The FSPF feature is enabled by default on all Fibre Channel switches. Except in configurations that
require special consideration, you do not need to configure any FSPF services. FSPF automatically
calculates the best path between any two switches in a fabric. Specifically, FSPF is used to:
Dynamically compute routes throughout a fabric by establishing the shortest and quickest path
•
between any two switches.
Select an alternative path in the event of the failure of a given path. FSPF supports multiple paths
•
and automatically computes an alternative path around a failed link. It provides a preferred route
when two equal paths are available.
