A wireless client roams from one Access Point to another Access Point using a different switch in a Cisco SD-Access network. If only a single Wireless Lan Controller in involved, what roaming methods is being used?
SDA Roaming
SDA supports two additional types of roaming, which are Intra-xTR and Inter-xTR. In SDA, xTR stands for an access-switch that is a fabric edge node. It serves both as an ingress tunnel router as well as an egress tunnel router.
When a client on a fabric enabled WLAN, roams from an access point to another access point on the same access-switch, it is called Intra-xTR. Here, the local client database and client history table are updated with the information of the newly associated access point.
When a client on a fabric enabled WLAN, roams from an access point to another access point on a different access-switch, it is called Inter-xTR. Here, the map server is also updated with the client location (RLOC) information. Also, the local client database is updated with the information of the newly associated access point.
In the Cisco Software-Defined Access, xTR stands for an access-switch that is a fabric edge node.

A. L3 Roaming is being used when a wireless client roams from one Access Point to another Access Point using a different switch in a Cisco SD-Access network and only a single Wireless Lan Controller is involved.
