The FSPF feature can be used on any topology.

Information About FSPF
FSPF is the protocol currently standardized by the T11 committee for routing in Fibre Channel networks. The
FSPF protocol has the following characteristics and features:
•
Supports multipath routing.
•
Bases path status on a link state protocol.
•
Routes hop by hop, based only on the domain ID.
•
Runs only on E ports or TE ports and provides a loop free topology.
•
Runs on a per VSAN basis. Connectivity in a given VSAN in a fabric is guaranteed only for the switches
configured in that VSAN.
•
Uses a topology database to keep track of the state of the links on all switches in the fabric and associates
a cost with each link.
•
Guarantees a fast reconvergence time in case of a topology change. Uses the standard Dijkstra algorithm,
but there is a static dynamic option for a more robust, efficient, and incremental Dijkstra algorithm. The
reconvergence time is fast and efficient as the route computation is done on a per VSAN basis.
The FSPF feature can be used on any topology.

FSPF Examples
Fault Tolerant Fabric Example
The following figure depicts a fault tolerant fabric using a partial mesh topology. If a link goes down anywhere
in the fabric, any switch can still communicate with all others in the fabric. In the same way, if any switch
goes down, the connectivity of the rest of the fabric is preserved.
