=> these parameters when they are set at the shared network level are inherited by subnet members. It is just for user convenience as usually all subnets of the same shared network share the interface the shared network is attached to and/or relays connected to the shared network. > - are "interface" and "relay" exclusive or can we have both ? => they are not exclusive but topologies with both are uncommon. Please note the localization process is the same for ISC DHCP and Kea: it follows the standard so selectors are used in the same order, and in both when shared networks are used the "selected subnet" is in fact the selected shared network: next steps will iterate through members, in Kea starting by the selected subnet.
