Public bug reported: If you have a subnet with 2 routers and you create and then delete a VM it may happen that an old ARP entry may persist. If you create another VM with the same IP and the ARP update goes to the other router you have a VM which isn't reachable via one router since the ARP entry is wrong.
A solution would be to update all router ports and not just one. ** Affects: neutron Importance: Undecided Assignee: Christoph Manns (christoph-manns) Status: In Progress -- You received this bug notification because you are a member of Yahoo!
