[Bug 1750121] Re: Dynamic routing: adding speaker to agent fails

[Dr. Jens Harbott]

@David: I have not been able to reproduce the error on xenial with
queens UCA. Your logs look like you are running without the patch
applied. Can you doublecheck that you did install the patched packages?
Can you set "debug=true" in /etc/neutron/bgp_dragent.ini and post logs
from that?

>From my POV the pkg works as expected, so I'd set "verification-queens-
done" but I don't want to override your report without your feedback.
I'll do another test on bionic tomorrow.

Bug description:
  SRU details for Ubuntu
  ----------------------
  [Impact]
  See "Original description" below.

  [Test Case]
  See "Original description" below.

  [Regression Potential]
  Low. This is fixed upstream in corresponding stable branches.

  
  Original description
  --------------------
  When following https://docs.openstack.org/neutron-dynamic-routing/latest/contributor/testing.html everything works fine because the speaker is scheduled to the agent automatically (in contrast to what the docs say). But if I remove the speaker from the agent and add it again with

  $ neutron bgp-dragent-speaker-remove 0159fc0a-22de-4995-8fad-8fb8835a4d86 bgp-speaker
  $ neutron bgp-dragent-speaker-add 0159fc0a-22de-4995-8fad-8fb8835a4d86 bgp-speaker

  the following error is seen in the log:

  Feb 17 10:56:30 test-node01 neutron-bgp-dragent[18999]: ERROR
  neutron_dynamic_routing.services.bgp.agent.bgp_dragent [None req-
  da9a22ae-52a2-4be7-a3e8-2dc2dc970fdd admin admin] Call to driver for
  BGP Speaker d2aa5935-30c2-4369-83ee-b3a0ff77cc49 add_bgp_peer has
  failed with exception 'auth_type'.

  The same thing happens when there are multiple agents and one tries to
  add the speaker to one of the other agents.
