2019-04-18 05:47:42 -0500 回答问题 External network with more than one VLAN not working in Stein Release.

Hi Mark, thanks for your answer. I'm not sure how to do what you asked for.

Also, from what I understood: the parameters "gateway_external_network_id" and "external_network_bridge" should be deprecated. is that correct?

Any suggestion how to apply the modification ypu have suggested in the configuration file?

Thx

2019-04-15 04:44:53 -0500 问了问题 External network with more than one VLAN not working in Stein Release.

Hi all, I'm pretty desperate, I hope you can give me a helpful tip. A few days ago I've deployed Openstack Stein using kolla-ansible. The Deployment itself was ok. I've configured the interface bond0 as the "neutron_external_interface" in the /etc/kolla/globals.yml file. On the bond0 there are 6 VLANs/subnets configurated on external Switch/Router side.

My goal is to configure all those VLANs/networks on Openstack as External Networks. The first VLAN configured works perfectly, but from the second VLAN doesn't work. When I try to configure a Router connected to the second VLAN/network I got this error on the file log /var/log/kolla/neutron/neutron-l3-agent.log:
