[NETVIRT-1412] the br-int has two same vxlan tunnels .

Wed, 22 Jan 2020 05:27:16 +0000

I modify the etc file like this:

1、{odl_dir}/etc/opendaylight/datastore/initial/config/genius-itm-config.xml ：

<def-tz-enabled>false</def-tz-enabled>

<gpe-extension-enabled>true</gpe-extension-enabled>

2、{odl_dir}/etc/opendaylight/datastore/initial/config/netvirt-elanmanager-config.xml ：

<auto-config-transport-zones>true</auto-config-transport-zones>

<use-of-tunnels>true</use-of-tunnels>

After the vm is created ,the vxlan tunnels are also built.

But there were two same vxlan tunnels. For example:

[root@wlz-controller odl]# ovs-vsctl show
e3894f29-cb8b-484e-a711-98411854e978

Bridge br-int
Controller "tcp:172.23.27.12:6653"

Port br-int
Interface br-int

Port "tun9285edd6d47"

Port "tapc5d79335-8b"

[root@wlz-controller odl]# ovs-ofctl show -O Openflow13 br-int

It shows that two same vxlan tunnels were bulit and one of them did not have port number.
