NetIron CER2024 virtual interface MAC address

Hello all,

I newbie working with Brocade devices, i have couple Brocade switches ( ~ 7x FWS624G) and new few days ago NetIron CER2024, I have a plan deploy this device as central router for connection LAN to internet.

From central router (Netiron) i have two L2 transport (with vlan support) to my LAN, i need use it both, because I provide internet connection on wide area and small area routers have differnt gateway.

Iam using trunk ports on Netiron so, traffic is tagged to different vlans, on vlans i set virtual router interface with IP address.

My problem is that router have same MAC address  on diffent virtual-router interfaces and that cause me (and my lan switches)  problem,

because at this time it's not posible have two separate vlans from one area router to central router (netiron), each vlan via different L2 transport (i have my area router connect with fws624 switch as trunk port, fws624 see netiron mac on both directions=L2 transport).

Net iron configuration and interface bried

As you can see, mac adress virtual interface 101, 102, ... and port 1/7, 1/9 is same 748e.f83c.da81,

in product datasheet is note, that mac is derived from first port 1/1 MAC.

But I need different mac adress on virtual interface, ideally derived from physical port MAC.

Is there way howto change this behavior?
