Title:
floating ip can‘t work because instance mac address conflict
Status in neutron:
Expired
Bug description:
Problem Description
=============================
neutron network mode is:
linux bridge + vxlan + l2pop
1. Create an instance, fixed_ip is allocating by dhcp agent.
2. Associate a floating_ip to the instance, then ssh or ping floating_ip.
3. Delete the instance, floating_ip is disassociated.
4. Create another instance, specify the same fixed_ip in step 1 which dhcp
agent auto allocated.
5. Associate the same floating_ip in step 2 , then ssh or ping floating_ip
will failed.
The reason for this issue is the arp entry in router namespace is old
instance mac address.
