well, I can see nodes that move between topologies, some
where RA is used/prefered and some where DHCP is used prefered.
historically, the SA's for DHCP service are distinct from the
SA's who manage routing, so moving forward, we are providing
a tool to each community that performs essentially the same
task. The end systems have had to deal with getting IP
addresses assigned from multiple places (static, RA, DHCP)
already - listing DNS server preference when there are
multiple inputs -can't- be that hard.
And its not like the IETF has not promoted two solutions
in the past... can you say OSPF and ISIS? Sure you can.
