Public bug reported:
Keepalived doesn't send gratuitous ARP on receiving SIGHUP. This makes
floating IP, which was previously associated with a port on different HA
router, inaccesible until local ARP cache is invalidated.
Steps to reproduce:
Have two networks and two HA routers
Associate floating IP to port on first router
Ping the floating IP from a different node than the node hosting router (this
creates arp entry on local machine)
Disassociate floating ip and associate it to the second router
- floating ip is not pingable as it contains wrong destination ip
address
