commit 452b2824125641128b5297fcf84de090e0763740 Author: LIU Yulong <[email protected]> Date: Sat Sep 29 18:04:10 2018 +0800 Trigger router update only when gateway port IP changed During the ha router state change event, the gateway port only changed the L2 binding host. So l3 agent has the entire gateway port information. It is not necessary to send a router_update message to l3 agent again. Closes-Bug: #1795127 Change-Id: Ia332421aff995f42e7a6e6e96b74be1338d54fe1 ** Changed in: neutron Status: In Progress => Fix Released -- You received this bug notification because you are a member of Yahoo!

Example: For dvr ha router, assuming it connected to public network and private network. In dvr_snat namespace, this router will have sg-device and qg-device in the snat namespace. When a HA state change happened. The sg-device related port and qg-device related port will update port binding host. Each one will send a router_update message to dvr_snat node. This will cause dvr ha router be process multipe times. Reproduce: kill the router 'master' keepalived instance in the dvr_snat node, manually produce a HA router state change.
