commit 3593620faa37322a1aaf1ce0c0ae3065ec623c2f Author: Yaohua Yan <yanyao...@cloudin.cn> Date: Mon Feb 27 22:26:08 2017 +0800 Change the way to distinguish the port type In delete_port_postcommit, a DVR port (port['device_owner'] = DEVICE_OWNER_ROUTER_SNAT) can match on l2pop_db.HA_ROUTER_PORTS[1], but can not get any fdb entries by _get_ha_port_agents_fdb. Then, the fdb_entries[network_id]['ports'] is been overwritten by {}. So the associated flow entries will not be deleted. Closes-Bug: #1668277 Change-Id: I7b621157fe85945acd99e4f08b6370d2f9c3d44d ** Changed in: neutron Status: In Progress => Fix Released -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1668277 Title: When enable l2pop, after deleting the DVR port, the associated flow entries still exists. Status in neutron: Fix Released Bug description: This results in a large number of useless flow entries in the br-tun flow table, and they will not be aged. Steps to reproduce: 1. Create a DVR router neutron router-create Router --distributed True --ha False 2. Create an internal network and a subnet neutron net-create Network neutron subnet-create Network 10.0.0.0/24 --name Subnet 3. Set gateway and add subnet to Router neutron router-gateway-set Router ext-net neutron router-interface-add Router Subnet 4. Boot an instance in Network nova boot --image <image_id> --flavor <flavor_id> --nic net_id=<net_id> VM 5. Login into VM using ssh or VNC console, and ping the Router to confirm network connectivity ping 10.0.0.1 6.
