Howto pinn/bind physical nic to the same interface number?

Background

I have an application that depends on being able to communicate with a specific interface card defined in a config file looking like below, %8 specifies Interface number

 <ipv6addresses>
      <address>de70::6aab:10.1.1.41%8</address>
      <address>de70::6aab:10.1.1.42%8</address>
      <address>de70::6aab:10.1.1.43%8</address>
      <address>de70::6aab:10.1.1.44%8</address>
    </ipv6addresses>

 

My interfaces (route print)

Interface List

 6aab...94 f1 <redacted> ......QLogic BCM57810 10 Gigabit Ethernet  #8

 13...94 f1 <redacted> ......QLogic BCM57810 10 Gigabit Ethernet  #9

 10...94 f1 <redacted> ......QLogic BCM57810 10 Gigabit Ethernet  #0

 22...94 f1 <redacted> ......QLogic BCM57810 10 Gigabit Ethernet  #7

 19...94 18 <redacted> ......Intel(R) I350 Gigabit Network Connection #2

 12...00 00 00 00 00 00 00 e0 Microsoft ISATAP Adapter <- MUST ALWAYS BE THIS INTERFACE

  1...........................Software Loopback Interface 1

  2...00 00 00 00 00 00 00 e0 Microsoft ISATAP Adapter #2

  8...00 00 00 00 00 00 00 e0 Microsoft ISATAP Adapter #3

 18...00 00 00 00 00 00 00 e0 Microsoft ISATAP Adapter #4

  5...00 00 00 00 00 00 00 e0 Microsoft ISATAP Adapter #5


My problem is that recently the interface numbers changed making the config file setting invalid and the application stopped working. I was told it happened after the application crashed.

Temporary solution:
Solving the problem for now was easy, update the xml file by changing %8 to %12 and start the services related to the application and it started as it should.

Looking for a permanent solution

On Microsoft technet I got the suggestion that this an be solved using software.

On this server, HP Enterprise Converged Network utility installed. I found no relevant settings in this application. Does HP has another tool to accomplice this?
