RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description David Sommerseth 2015-07-17 16:50:04 UTC 
Description of problem:
When configuring network devices in an environment where the DHCPv6 server also can provide secondary IPv6 addresses, NetworkManager will only configure the primary IPv6 address.  Running dhclient -6 manually configures all the DHCP provided IPv6 addresses.

Version-Release number of selected component:
NetworkManager-1.0.2-1.fc22.ppc64le
dhcp-client-4.3.2-2.fc22.ppc64le

How reproducible:
Always.

David or Beniamino do we have dhcpv6 networks somewhere in RH?

Not inside RH, but the Open Power Hub in Brno have such a setup.  I have a VM running there and can help out with any type of testing.
Comment 5 David Sommerseth 2015-08-11 12:06:52 UTC 
just a remark regarding not inside - I meant, I don't know of any dhcpv6 enabled networks inside RH, at least none with also provides secondary addresses too.
