Comment 4 for bug 1673911

Again, sorry for failing to follow up on this.

You correctly guessed that exabgp 3.x is not recent enough for networking-bagpipe.
You need to use a exabgp >= 4.0.x

The next release of networking-bagpipe shipping with bagpipe-bgp in it will soon be released and will be installable with:

  pip install -c https://git.openstack.org/cgit/openstack/requirements/plain/upper-constraints.txt?h=stable/pike networking-bagpipe=7.0.0

In the meantime, you need to git clone, installing with "pip install -c https://git.openstack.org/cgit/openstack/requirements/plain/upper-constraints.txt?h=stable/pike . " will install networking-bagpipe with correct dependencies.
