I see. I had been using "Automatic, DHCP only" because I thought that when using "Automatic" nothing happened (no global IP address was obtained). However, I just tried and it worked, and a default IPv6 route was even installed. I realize now that it is not that nothing happened but that things took a long time (a couple of minutes) to happen -- first, there was a delay to get an IPv6 address, and then there was a delay (after the interface had a global IPv6 address) to see the default route installed. Are these delays normal; do they depend on the frequency of router advertisements? If so, can NM not elicit a router advertisements by sending a router solicitation? If that is what is supposed to happen then I don't understand the delays. In contrast, IPv4 configuration is immediate.

Yes, things do work now that I went with "Automatic" configuration albeit with a delay of a couple of minutes until I have full connectivity. > Also make sure that the connection is not never-default (by default it > is never-default=no): > > nmcli connection show $CON_NAME | grep ipv6.never-default Yes, that was not set. > Also note, you can configure the ipv6.gateway property manually too. Right, I figured, but that would cause problems as I move from network to network so I was trying to get this to work with automatic configuration. In any case, changing from "Automatic, DHCP only" to "Automatic" did the trick; thanks! I can live with the delay that I am seeing.
