[Bug 1498987] [NEW] DHCP agent should provide ipv6 RAs for isolated networks with ipv6 subnets

 

Public bug reported:

Currently, if there is no router attached to a subnet, then instances
cannot walk thru IPv6 address assignment because there is nothing on the
network that multicasts RAs that would provide basic info about how ipv6
addressing is handled there. We can have DHCP agent to run radvd in that
case. Then instances would be able to receive IPv6 addresses on isolated
networks too.

We could try to rely on https://tools.ietf.org/html/rfc4191.
