Hi guys:
   
The bug has be reported on https://bugs.launchpad.net/neutron/+bug/1541738
    
The flow in br-tun as below is generated by learning flow, and not updated immediately after vm live migration.


Original flow:
cookie=0x0, duration=194.884s, table=20, n_packets=0, n_bytes=0, hard_timeout=300, idle_age=194, priority=1,vlan_tci=0x0306/0x0fff,dl_dst=5a:c6:4f:34:61:06 actions=load:0->NXM_OF_VLAN_TCI[],load:0x1ef->NXM_NX_TUN_ID[],output:24
  
Updated flow:
cookie=0x0, duration=194.884s, table=20, n_packets=0, n_bytes=0, hard_timeout=300, idle_age=194, priority=1,vlan_tci=0x0306/0x0fff,dl_dst=5a:c6:4f:34:61:06 actions=load:0->NXM_OF_VLAN_TCI[],load:0x1ef->NXM_NX_TUN_ID[],output:26


Anyone has idea how to update this flow proactively.thanks!
