Yes:
flashman ~ % ndp -p
2001:708:20:e336::/64 if=em0
flags=LAD vltime=2592000, pltime=604800, expire=29d23h59m58s, ref=2
advertised by
fe80::200:5eff:fe00:109%em0 (unreachable)
flashman ~ % ndp -r
fe80::200:5eff:fe00:109%em0 if=em0, flags=, pref=medium, expire=29m57s
The ndp entry for the router is incomplete after autoconf (hence
"unreachable"). ping6'ing it makes it reachable *and* seems to add the
appropriate on-link route, though.
