Description
After created two Physical Switch by Open vSwitch HWVTEP Emulator, tunnel I/F is created only in one LogicalSwitch when creating L2GW CONNECTION
By confirming with command "ovs-vsctl show", we found that the tunnel I/F was displayed only for a moment and disappeared right away. Certainly, the communication failed.
The Virtual L2 network configuration we want to create is as below:
With one L2GW node, connect one virtual LAN (vxlan) and one virtual LAN (vlan) which is on multiple (two or more) physical lines by L2
------------------(name:test-nw)
(vxlan) | |
| ----- | ||
| +--- | gw1 | --+ |
| ----- | ||
| --------------- vlan:2222(Physical line#1) | ||
| ----- +------ |
gw2 | --+ ----- |
--------------- vlan:2222(Physical line#2)
Physical configuration of L2GW Node:
---------------------------------------------------
| L2GW Node | ||||
| --------------------- |
||||
| Physical Switch(1) | Physical Switch(2) | |||
| --------------------- |
||||
| ----------------- |
||||
| Physical Port(1) | Physical Port(2) |
---------------------------------------------------
----- Physical line#1 |
----- Physical line#2
L2GW GATEWAY/CONNECTION creation command :
neutron l2-gateway-create gw1 --device name=Physical Switch(1),interface_names=Physical Port(1)
neutron l2-gateway-create gw2 --device name=Physical Switch(2),interface_names=Physical Port(2)
neutron l2-gateway-connection-create gw1 test-nw --default-segmentation-id 2222
neutron l2-gateway-connection-create gw2 test-nw --default-segmentation-id 2222
P.S
We know the following configuration can also realizes the Virtual L2 network configuration we want to create.
But Load balancing is impossible as Open vSwitch HWVTEP Emulator (ovs-vtep) process starts for each physical switch.
