Abstract
A primary server and a backup server that both run a RADIUS client in a cold start configuration share a single IP address that includes a limited number of message identifiers (MIDs). The primary server and the backup server each have a small number of fixed message identifiers. In addition, a large number of shared message identifiers are used by the primary server, and then used by the backup server a predetermined time after the primary server fails.
