Re: [Openstack-operators] Openvswitch flat and provider in the same bond

2017-04-19 Thread Dan Sneddon
If all of the VLANs are tagged, then I am having a hard time imagining why you want to use only one of them as a flat network. The only difference between a VLAN network and a flat network in Neutron is that OVS handles tagging/untagging on VLAN networks and flat networks are untagged. It is poss

One small change for us recently is that we removed the vlan-splinters piece on eth0 and eth2 during the creation of the bond. Other than that – I am not really sure what to tell you. We use to do things using linux bonding with bond., however when we went to production no traffic actually flo

Thx Kris. If I map flat with br-flat and I add bond.567 interface to br-flat, it does not work ? Regards Ignazio Il 19/Apr/2017 21:20, "Kris G. Lindgren" ha scritto: We handle this a different way, I want to look to see if we can redo it, so it requires less pre-configuration on the host. Howe

Hi Dan, on the physical switch the 567 is not the native vlan but is tagged like 555 and 556. I know I could set 567 as a native vlan to receive it untagged. But if I would like more than one flat network ? I am not skilled in networking but I think only one native vlan can be set in switch. Any f
