Public bug reported: HA/legacy router gateway secondary IPs was removed Unexpectedly.
First it process the external gateway: https://github.com/openstack/neutron/blob/master/neutron/agent/l3/router_info.py#L1035 https://github.com/openstack/neutron/blob/master/neutron/agent/l3/router_info.py#L817 Then process the router floating IPs: https://github.com/openstack/neutron/blob/master/neutron/agent/l3/router_info.py#L828 And then, the gateway secondary IPs has a /32 prefix, which will be treated as `fips_to_remove`: https://github.com/openstack/neutron/blob/master/neutron/agent/l3/router_info.py#L290 Some related code: existing_cidrs = self.get_router_cidrs(device), this existing_cidrs including the gateway secondary IPs: https://github.com/openstack/neutron/blob/master/neutron/agent/l3/router_info.py#L304 gateway secondary IPs were removed here: https://github.com/openstack/neutron/blob/master/neutron/agent/l3/router_info.py#L332 DVR/DVR_SNAT_HA router does not have this issue. ** Affects: neutron Importance: Undecided Assignee: LIU Yulong (dragon889) Status: New ** Summary changed: - HA: ha router gateway secondary IPs was removed Unexpectedly + HA/legacy router gateway secondary IPs was removed unexpectedly -- You received this bug notification because you are a member of Yahoo!
