If we are unable to solve this within the context of Neutron we should
at least document this limitation in the networking guide under the HA
scenario section.

Title:
  Problem in l3-agent tenant-network interface would cause split-brain
  in HA router

Status in neutron:
  Confirmed
Status in openstack-manuals:
  New

Bug description:
  Assuming l3-agents have  1 NIC (ie eth0) assigned to tenant-network (tunnel) traffic and another (ie eth1) assigned to external network,.
  Disconnecting eth0 would prevent keeplived reports and trigger one of the slaves to become master. However, since the error is outside the router namespace, the original master is unaware of that and would not trigger "fault" state. Instead it will continue to receive traffic on the, yet active, external network interface - eth1.
