As described in RFC3041 (and in its successor draft), When a temporary address becomes deprecated, a new one should be generated. (from section 3.4 of RFC3041). FreeBSD should behave that way (on my laptop running 6.2-PRERELEASE, I have two temporary addresses; one is preferred and the other is deprecated). JINMEI, Tatuya Communication Platform Lab.

If you do not want to disclose your internal information but want to get an answer, I'd recommend you to reproduce the situation using prefixes for documentations/examples like 192.0.2.0/24 and 2001:db8::/32 and show every detail. > My current interface configuration is > vlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 > inet xxx.xxx.xx.xx netmask 0xffffff00 broadcast xxx.xxx.xxx.xxx > inet6 fe80::211:xxxx:xxxx:xxxx%vlan0 prefixlen 64 scopeid 0x5 > inet6 2xxx:xxxx:xxxx:: prefixlen 64 anycast > inet6 2xxx:xxxx:xxxx:0:211:2fff:xxxx:xxxx prefixlen 64 > inet6 2xxx:xxxx:xxxx:0:54b:5960:xxxx:xxxx prefixlen 64 deprecated autoconf temporary pltime 0 vltime 509995
