teaming failover between activebackup ports results in loss of IP connectivity

Solution Unverified - Updated -

Issue

  • teaming failover between activebackup ports results in loss of IP connectivity
  • Team switch between ports in active-backup mode, while host lost connection (IP in team is unreachable)
  • When switching the port or slave of a team, ARP is sent which causes the network to learn the wrong MAC address for the team's IP address or VIP

Environment

  • Red Hat Enterprise Linux 7.6 (kernel-3.10.0-957.el7 series) or earlier
  • Teaming link aggregation using "activebackup" runner
