I did these:
- edit /etcsysctl.conf so that ddb.console=1
- rebooted
- in another shell ran
$ tcpdump -s1500 -Xvvi re0 icmp6
('<interface> proto icmp6' gave 'Syntax Error')
- did ctrl-alt-esc, got
Stopped at Debugger...
ddb>w nd6_debug 1
nd6_debug 0 = 1
ddb>c
- ran
$ rtsol -D re0
- and got:
checking if re0 is ready...
re0 is ready
set timer for re0 to 0:481765
New timer is 0:00481718
timer expiration on re0, state = 1
send RS on re0, whose state is 2
set timer for re0 to 4:0
New timer is 4:00000163
received RA from fe80::21f:f3ff:fe40:ac51 on re0, state is 2
stop timer for re0
there is no timer
- in the other tcpdump shell saw this:
tcpdump: listening on re0, link-type EN10MB

The 'unsupported option 25' looks to my untrained eye as the culprit.
Does that help you?
