Public bug reported: As part of BP multiple IPv6 prefixes, we can have multiple IPv6 prefixes on router internal ports. Patch, I7d4e8194815e626f1cfa267f77a3f2475fdfa3d1, adds the necessary support for a legacy router.
For an HA router, instead of configuring the addresses on the router internal ports we should be updating the keepalived config file and let keepalived configure the addresses depending on the state of the router. Following are the observations with the current code for an HA router. 1. IPv6 addresses are configured on the router internal ports (i.e., qr-xxx) irrespective of the state of the router. As the same IP is configured on multiple ports you will notice dadfailed status on the ports. 2. Keepalived configuration is not updated with the new IPv6 addresses. ** Affects: neutron Importance: Undecided Assignee: Sridhar Gaddam (sridhargaddam) Status: In Progress ** Changed in: neutron Assignee: (unassigned) => Sridhar Gaddam (sridhargaddam) ** Changed in: neutron Status: New => In Progress ** Description changed: As part of BP multiple IPv6 prefixes, we can have multiple IPv6 prefixes on router internal ports.
