So how the DWDM is to be implemented, should have been asked first. It may be through the Dark fibre as you revealed, or can be implemented through FCIP aswell.  1). Here you are talking about the ISL ports (E ports with long wave GBICs), these can be in the default VSAN, i.e. VSAN 1, however VSAN 30 should be in the trunk allowed list of the ISL.  2). VSAN 30 will extend through the fabric on remote site as well, as it will be a part of the trunk allowed list of ISL.  3). On both the border switches (9513 & 9222) you will have to :           a). IVR enable.           b). IVR distribute.           c). IVR commit.           d). After this check that CFS application for switch is merged, using command, show cfs peer name ivr. Do this on both the border switches to confirm that the output lists both the switches. Now if zonning is configured from either of the border switch, followed by an IVR commit, then the zonning information will be passed on to the other switch as well.  Hope this answers your queries.
Hello guys,  Please answer my questions regarding IVR considering my design, see picture attached:  Considering all VSANs have unique id, so IVR-NAT is not required.  1) I am going to configure transit VSAN  30, this VSAN will only contain ports that provide DWDM connectivity ? 2)  I will create transit VSAN ( VSAN 30) on both 9513 and 9222i switch,  that will be the only VSAN allowd to be trunked, so essentially VSAN 30  will merge ? 3) IVR is enabled on both 9513 and 9222i, VSAN 10  needs to be able to talk to devices on VSAN 110, VSAN 20 needs to be  able to talk to devices in VSAN 200. When i run IVR Wizard for the very  first time, do i need to select VSAN 10, 110, 20, 200 and VSAN 30 which  is my transit VSAN ? 4) If i have a host that is directly  plugged-in into my edge 9134, can it be IVR zoned to an array plugged-in  directly into 9124e, considering 9134 and 9124e do not support IVR but  they are connected to switches that have IVR enabled.  Looking at my design are there any questions that i should be asking ?  Thank you very much  [IMAGE]
