The OnePopLoginPull configuration scenario provides a simple NIC resolution from a subscriber login name or IP address to an SAE reference.
Figure 1 shows the resolution graph for this scenario.
In the OnePopLoginPull scenario, SAE client agents read entries under o=umc, o=servers, o=sspadminurls in the Juniper Networks database to determine which SAEs are active. They also periodically check if other SAEs have become active. The SAE external interface for the active SAEs determines which SAE has a user session for the subscriber identified either by login identifier or IP identifier.
The OnePopLoginPull scenario includes the following SAE client agents:
