Why is ODL adding port eth1 to br-int by default

On my ODL and Openstack setup, after I configure the OVS switch to be managed by ODL, two bridges are created:

br-int and br-ex.

For some reason ODL seems to add port eth1 to br-int by default

ovs-vsctl show
    Manager "tcp:"
    Bridge br-int
        Controller "tcp:"
        fail_mode: secure
        Port "eth1"
            Interface "eth1"
                error: "could not open network device eth1 (No such device)"
        Port br-int
            Interface br-int
                type: internal
    Bridge br-ex
        Controller "tcp:"
        fail_mode: secure
        Port br-ex
            Interface br-ex
                type: internal
    ovs_version: "2.5.0"

On my setup I don't have eth1, instead its

enp0s3 enp0s8 enp0s9

I haven't configured eth1 anywhere, so why does this get added by default?

Hi Dave, Even i observed the same while trying out Berylium integration with OpenStack Mitaka. I was removing that port from br-int manually during the course of work. BTW which ODL are you working on ? --Regrads

Hi, I'm using packstack to install Newton with ODL Boron-SR1 (but got the same behavior with Berylium). Does your system function correctly? When I create VMs sometimes they get IPs via DHCP and sometimes they don't. It's very flaky.

Hi, I used Packstack to install Mitaka. System was functional and it was working good. FYI: http://sciencecloud-community.cs.tu.a...
