In addition, to support FCIP tunneling, we introduce the
VE_Port, or rather the
virtual E_Port created over the FCIP tunnel. Figure 2-6 shows an FCIP tunnel
between two SAN routers.

The VE_Port functions exactly like a normal E_Port, and a normal ISL is created
between the two VE_Ports.
2.3 Description of the routing solution
This example has a small Meta SAN, consisting of two edge fabrics of one switch
each and a single router backbone fabric. Each edge fabric has two connections
to the router for redundancy.
The fabric parameters are set as follows:
