MAC Masquerade

Hi Guys ,

i have a question about this article https://my.f5.com/manage/s/article/K3523, 

is it a mandatory to add 02 to mac address ? can it be for example 03? i tryied to add to traffic group and for some reason i think with 03  gratuitus arp was not being sent.

    Hi j30046616 , 

    I tried to break this rule before of flipping ( second-to-last bit from 0 to 1 ) and it didn't work.

    It's not depending only adding 02 hex , it's just a shorthand way to create a unique one. 

    If you look at the second example: 

     it just follows the rule of of flipping ( second-to-last bit from 0 to 1 )
