[Kea-users] One question on the subnet configuration

[Xiao, Yu (CCI-Atlanta)]

Hi experts,

I configured two client classes for my test RPDs. And I also configured three subnets for three different RPDs. I found that even in the subnet configuration, I have correlated the client-class “RPD_new” for that subnet 3 to use. But in reality, kea just ignored this configuration, and use the client class “RPD” for all 3 subnets. And because my test RPDs satisfied both “RPD” and “RPD_new” client classes, and my test RPD used the configurations in “RPD” instead of “RPD_new”.

Why the configuration “client-class” under “subnet6” won’t take effective as I thought?
