1761517 – [RHEL7] DHCP Stateful - Openstack DHCPv6 instance get no default gateway and is unable to send IPv6 traffic (Network unreachable errors).

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 Harald Jensås 2019-10-14 14:48:50 UTC

Description of problem:
IPv6 Openstack instance on dhcp-statefull address mode cannot communicate. (Network unreachable errors).

cloud-init by default configure IPV6_AUTOCONF=no in /etc/sysconfig/network

This set's /proc/sys/net/ipv6/ settings:
 accept_ra = 0
 autoconf = 0



[1] https://github.com/fedora-sysv/initscripts/commit/28745ca8101b47b8a33213cfc524a4ada742721b

Version-Release number of selected component (if applicable):
cloud-init-18.5-3.el7.centos.x86_64

How reproducible:


Steps to Reproduce:
1. Install Openstack
2. Create a flat provider network and add a ipv6 subnet on this network with:
 ipv6_address_mode: dhcpv6-stateful
 ipv6_ra_mode: dhcpv6-stateful
3. NOTE, no router was created, so Openstack does not do RA's in this case.
   radvd was set up with the following config on the provider network:
                  interface eth1 {
                    AdvSendAdvert on;
                    AdvManagedFlag on;
                    AdvOtherConfigFlag on;
                    AdvRASolicitedUnicast on;
                    AdvLinkMTU 1450;
                    prefix fd12:3456:789a:1::/64 {
                      AdvAutonomous on;
                      AdvOnLink on;
                    };
                  };
4. Deploy and instance on this network.

Actual results:
