I am wondering where you got the notation ":addrs#1:" from. Please
try the following:
em2:\
:mtu#1400:\
:addr0="3ffe:501:ffff:100::":prefixlen0#64:vltime0#12345:pltime0#12345:\
:addr1="3ffe:501:ffff:101::":prefixlen1#64:vltime1#12345:pltime1#12345:

Hi Hiroki,
I got that notation from here
http://www.freebsd.org/doc/handbook/network-ipv6.html. Okay, let me try
you're recommendation.
Thanks,
Hi Hiroki,
I confirmed verifying on 8.2, 7.2 and 4.11, the notation you've
suggested is working. In fact, I've tried at least 5 prefixes and it
works perfectly. Therefore, this is not a bug or design limitation in
the rtadvd but rather a configuration issue.
vulcan2# cat /etc/rtadvd.conf
em2:\
:mtu#1400:\
:addr0="3ffe:501:ffff:100::":prefixlen0#64:vltime0#12345:pltime0#12345:\
:addr1="3ffe:501:ffff:101::":prefixlen1#64:vltime1#12345:pltime1#12345:\
:addr2="3ffe:501:ffff:102::":prefixlen2#64:vltime2#12345:pltime2#12345:\
:addr3="3ffe:501:ffff:103::":prefixlen3#64:vltime3#12345:pltime3#12345:\
:addr4="3ffe:501:ffff:104::":prefixlen4#64:vltime4#12345:pltime4#12345:
