Title:
L3 HA keepalived config state becomes inconsistent when managing
floating ips
Status in OpenStack Neutron (virtual network service):
Fix Committed
Status in neutron juno series:
New
Bug description:
The Keepalived config becomes inconsistent, missing some/all floating
IP addresses on regeneration on the current master. Upon transition
this results in floating IP addresses being left configured on the
previous active master.
This occasionally results in network flaps for all addresses attached
to that tenants router.
Neutron L3 Agent checks what IPs are configured on the local interface
before it adds the Floating IP addresses, as keepalived holds the
configured state we need to check against keepalived not the system.
