  1. negotiate a RADIUS AAA server address and shared secret with an eduroam NRO, to be used as uplink for authentications.Then, either
    1a)  send all realms not belonging to another roaming partner to the eduroam servers (a "default" routing to eduroam). This is only possible if all other roaming partners at the hotspot are identifiable and can be enumerated.
    1b) use equipment that supports Passpoint R3 to allow identifying and forwarding of the thousands of realms in eduroam towards that one server (by leveraging the then-present RADIUS attribute "HS2.0 roaming consortium" [Vendor-Specific, Vendor 40808, Attribute 6] in the authentication request).
  2. get a roaming certificate for usage with RADIUS/TLS and Dynamic Server Discovery (e.g. from eduroam Operations directly) and look up DNS NAPTR records for the realm in question; the NAPTR labels being "x-eduroam:radius.tls" (if you have a RADIUS/TLS server certificate from eduroam) or "aaa+auth:radius.tls" (if you have any other server certificate). Connections should be attempted to all servers resulting from the respective DNS responses. Note: only a minority of eduroam IdPs currently use NAPTR records; not all eduroam realms will be reached with this configuration.

1b1a) is currently the most viable option.

There are currently no plans to move away from using the SSID "eduroam" as the single user-facing identifier for hotspots operated directly by an eduroam participating organisation. If this ever changes, the Roaming Consortium Organisation Identifier

00-1B-C5-04-6F [configured in end-user device to be displayed as: "eduroam®"]

is reserved for that purpose. It is configured in some supplicants but not expected to be emitted by any SP which has an SSID "eduroam" at this point.

However, eduroam SPs which deploy a separate onboarding SSID can benefit from the Online Sign-Up capabilities in Passpoint R2 and above. They should configure their eduroam SSID to emit the OSU (Online Sign-Up) portions of Passpoint and configure the OSU server URL as defined below as the target server for Online Sign-Up. Their onboarding SSID must then allow access for end-users to that URL and to eduroam CAT.
