Fabric formation

Brocade VCS Fabric technology leverages proven FC Fabric protocols to build a TRILL fabric. The main functions of the fabric formation protocols are as follows:

  • Assign the Brocade VCS Fabric-wide unique RBridge IDs (Domain ID Assignment).
  • Create the network topology database using link state routing protocol (Fabric Shortest Path First, or FSPF). FSPF calculates the shortest path routes to a destination RBridge.
  • Distribute fabric multicast traffic.
