FC-FC routing overview
The FC-FC routing service provides Fibre Channel routing between two or more fabrics without
merging those fabrics. For example, using FC-FC routing, you can share tape drives across multiple
fabrics without the administrative problems, such as change management, network management,
scalability, reliability, availability, and serviceability, that might result from merging the fabrics.
Be aware that there are different routing terminologies in use:
FC routing is only in a single fabric (Layer 2 routing). This type of routing is discussed in
Chapter 4, “Routing Traffic”.
FC-FC routing is routing between two fabrics (Layer 3 routing) and is discussed in this chapter.
FC-FC routing supports connectivity between the following types of fabrics:
Fabric OS and Fabric OS
Fabric OS and Brocade Network OS
Fabric OS and M-EOS
