During AIO-DX IPv6 node installation, the management address for
controller-1 set by dhclient receives a "/128" prefix length. The
cause comes from DHCPv6, which does not inform a prefix length on its
negotiation. The prefix should be learned via RA messages.
Since the internode IPv6 communications in StarlingX do not contain
a router and RA is in principle disabled on the management network,
we must set the system with the default prefix length of 64. A similar
patch was done for Centos.
Test Plan
[PASS] Install AIO-DX on IPv6 network, it is correctly setting the
controller-1 mgmt ip address after the first boot.

Subject: [PATCH] Set the default prefix length to 64
|
|
|
|
Since the StarlingX internode communication happens without a L3 router,
|
|
the hosts will not be able to see each other with prefix length of 128.
|
|
|
|
This commit sets the default value to 64
