I have a couple of hosts on different networks running 11.1-RELEASE amd64. 
Neither host will auto-configure its IPv6 address, even though valid router 
advertisements[1] are present. Both hosts have two oce(4) interfaces aggregated 
in fail-over mode via lagg(4). The lagg interface is configured thusly 

ifconfig_lagg0="inet xxx.xxx.217.100/25 laggproto failover laggport oce0 
laggport oce1"
ifconfig_lagg0_ipv6="inet6 accept_rtadv"

The running interface looks like this:
lagg0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        ether ac:16:2d:1e:b8:80
        inet xxx.xxx.217.100 netmask 0xffffff80 broadcast xxx.xxx.217.127 
        inet6 fe80::ae16:2dff:fe1e:b880%lagg0 prefixlen 64 scopeid 0xc 
        media: Ethernet autoselect
        status: active
        groups: lagg 
        laggproto failover lagghash l2,l3,l4
        laggport: oce0 flags=5<MASTER,ACTIVE>
        laggport: oce1 flags=0<>

ndp(8) shows only:
Neighbor                             Linklayer Address  Netif Expire    S Flags
fe80::ae16:2dff:fe1e:b880%lagg0      ac:16:2d:1e:b8:80  lagg0 permanent R

Other hosts (running RedHat 6) on the same network SLAAC just fine. Does anyone 
have insight into this problem or suggestions for troubleshooting?
