Comment 24 for bug 1895822

@Alex per comment #22 agree, it *is* there in the config - if you see my comment #21 [2] and [3] repeated here are pointing to the os-net-config for deployment [2] and upgrade [3] and indeed both have the br-ex.

However the resulting configuration *on the node* is missing the br-ex e.g. looking at [1] no mention of br-ex. Compare that with [4] from a standalone job you can see the br-ex configured and with has routes for it too
