A wireless client roams between APs on different switches in SD-Access with a single WLC involved. Which roaming method is used?

In an SD-Access fabric, when a wireless client roams between APs connected to different edge nodes (switches), and these edge nodes are part of the same fabric site (meaning they share the same WLC and control plane), an inter-xTR (Extended Node) roaming method is used. The xTR is the term for the fabric edge node. This method leverages the VXLAN overlay to maintain the client's IP address and session as it moves between different fabric edge nodes. L3 roaming typically refers to roaming across different subnets or WLCs, which isn't the case here as it's within the same fabric site and WLC. Auto anchor (or guest anchor) is a traditional WLC feature used for guest access or roaming between different mobility groups, not within a single SD-Access fabric site. Bridged roaming is a general term that can apply to various scenarios but isn't the specific SD-Access mechanism for this type of roam.
