I can't tell from the host; I'll have to engage the networking guys.

That's a reasonable hypothesis, but it's contradicted by further testing. I 
started a packet capture on the host:

# tcpdump -Z gcr -w /tmp/hostname.pcap -i lagg0 ip6

Then I ran rtsol on the host again:

# rtsol -dD lagg0

The output was as before, but the pcap[1] shows that RAs were received. In 
response to the RSs sent by the host (frames 1 and 2), both routers on this 
network responded with RAs (frames 3 and 4). So it would appear that the 
disconnect is not between the routers and lagg0, rather it's between lagg0 and 
the host's IPv6 stack. tcpdump saw the RAs on lagg0, but rtsol did not.

Could it be that the router replies are out of spec somehow and are being 
discarded? Where does debug output from net.inet6.icmp6.nd6_debug=1 go?
