The Directors on each side (48K’s) have E ports connected to EX ports on the FC Routers (7500’s). The 7500’s have VE to VEX FCIP Tunnels created as well. I have created aliases for USPV ports and a Solaris machines WWN’s as well as created LSAN zones on each switch. The 7500’s see the devices from their local sides but don’t seem to know how to get across the FCIP as the host does not see the USPV target ports or LUNs.
Do you know if this configuration is supported in the way I have it configured?
host1 <-> 48k-1 (E) <-> (EX) 7500-1 (VEX) <----> FCIP over 10Gb/s <----> (VE)7500-2 (EX) <-> (E) 48k-2 <-> storagearray2

--->>> the link between is 10G....
Is the link connected trough a Optical Metro Switch ?
is the tunnel a Dark tunnel ?
--->>> but we are using 1G connections....
what Model of SFP your use beetwen the 7500 and this 1G/s connection ?

The issue ended up being an illegal configuration.
I was trying to do E-EX-VE-VEX-EX-E, you cannot have an EX and VEX on the edge and backbone fabrics.
My fix was to do E<->E-VE<->VEX-E<->E, so i merged the local fabrics and kept the remote fabrics un-merged with the VEX port.
Attaching the official 7500 Configuration options doc.

shows two fabrics merged into a single fabric using FCIP tunnels.
Fabric interconnected using FCIP
shows two SAN18B-Rs connected using an FCIP tunnel to form an IFL link. Fabrics are unmerged.
These configuration from IBM System Storage Brocade Multiprotocol Routing An Introduction and Implementation.

The 2nd Diagram is not a legal configuration.
you can not do double backbone. i.e. EX port to VEX to EX
you can do either EX to VE-VE to EX or E to VE-VEX to E
only having a single Backbone fabric.
Can you supply the link to the document you found the above diagram documented as legal ?

THank you !
how to connect Edge Fabirc1 <-- IFL --> route <-- IFL --> route <-- IFL-->Edge Fabirc 2 ,I do not understand in this diagram.

please refer to the Rules outlined in the same redbook section 3.3.1 FC-FC routing and FCIP distance extension on page 54.
The diagram you point to breaks these rules and I will get that remedied.
for your solution you must either
ISL - IFL - ISL
IFL - ISL - IFL
both methods will not merge the fabrics and do not break the rules.
