Hello, I have a question about the l2gw. I did a deployment, I described the steps here: https://review.openstack.org/#/c/453209/
The unicast traffic works fine, but I dont understand what is the idea behind the handling of the broadcast traffic. Looking at openvswitch: I obtain the uuid with `vtep-ctl list-ls` vtep-ctl list-remote-macs <uuid> In this output I get an entry for each VM that has an interface in the L2 network I am bridging: ---- # vtep-ctl list-remote-macs <uuid> ucast-mac-remote fa:16:3e:c2:7b:da -> vxlan_over_ipv4/10.1.1.167 mcast-mac-remote ----- The ucast-mac-remote entry is created by Openstack when I start a VM. (Also it is never removed when I delete the instance, is this a bug ? ) Note that 10.1.1.167 is the IP address of the hypervisor where the VM is running. But mcast-mac-remote is empty. So this means that ARP learning for example works only in 1 way. The VM in openstack does not receive any broadcast traffic, unless I do manually: vtep-ctl add-mcast-remote ee87db33-1b3a-42e9-bc09-02747f8a0ad5 unknown-dst 10.1.1.167 This creates an entry in the table mcast-mac-remote and everything works correctly. Now I read here http://networkop.co.uk/blog/2016/05/21/neutron-l2gw/ about sending add-mcast-remote to the network nodes and then doing some magic I dont really understand. But I am confused because in my setup the tenant does not have a L3 router, so there is not a qrouter namespace for this network, I was planning to keep the network node out of the game. Is anyone running this in production and can shed some light ? thanks Saverio -- SWITCH Saverio Proto, Peta Solutions Werdstrasse 2, P.O.
