Pool member in Unlicensed status

Hi everybody,

I am building a virtual lab for DNS module. I configured a simple wideip resolution using one datacenter, 2 links one ltm with two virtual server, one virtual server per link. I create a wideip pool with this two VS and round robin balancing method. I create a wideip with this pool, but when I try to see the members status, one of them show unlicensed status with reason Not authorized.

I am using 12.1 TMOS version. I try this solution: https://support.f5.com/kb/en-us/solutions/public/15000/800/sol15834.html but I am not setting any linkcost balancing.

Someone know why I get that status?
