Description of PR The docker-ptf PY3 only image uses ExaBGP v4. The ExaBGP v4+ requires process API to acknowledge messages from ExaBGP else the server blocks after a while and hangs. This causes BGP timeouts in our stress tests. This PR fixes the issue. Summary: Fixes # (issue) Not applicable to backport since it only applies to docker-ptf PY3 only image. Approach What is the motivation for this PR? The docker-ptf PY3 only image uses ExaBGP v4. The ExaBGP v4+ requires process API to acknowledge messages from ExaBGP else the server blocks after a while and hangs. This causes BGP timeouts in our stress tests. This PR fixes the issue. How did you do it? Set exabgp.api.ack to false. How did you verify/test it? Ran tests/stress/test_stress_routes.py on 7050cx3 to confirm. Any platform specific information?
