Chapter 11 Troubleshooting VSANs, Domains, and FSPF
FSPF Issues
FSPF Issues
The implementation of VSANs dictates that each configured VSAN support a separate set of fabric
services. One such service is the FSPF routing protocol, which can be independently configured per
VSAN. Therefore, within each VSAN topology, FSPF can be configured to provide a unique routing
configuration and resulting traffic flow. Using the traffic engineering capabilities offered by VSANs
allows greater control over traffic within the fabric and higher utilization of the deployed fabric
resources.
This section describes how to identify and resolve Fabric Shortest Path First (FSFP) problems. It
includes the following topics:
• Troubleshooting FSPF, page 11-24
• Loss of Two-Way Communication, page 11-28
