[BGPCEP-914] Controller-exabgp session fails when route-refresh is true

Wed, 29 Jul 2020 17:25:36 +0000

The issue is only happening in Aluminium and it is tracked here: https://logs.opendaylight.org/releng/vex-yul-odl-jenkins-1/bgpcep-csit-1node-userfeatures-all-aluminium/130/robot-plugin/log.html.gz

Controller does not respond to exabgp openconfirm (keepalive) message when 'route-refresh' capability is enabled in exabgp:
