Then, ODL try to setup again the BGP session which ended for the same reason going into an infinite loop of BGP session open / close until the BGP peer is removed. Karaf log contains the following error:</p> <div class="preformatted panel" style="border-width: 1px;"><div class="preformattedContent panelContent"> <pre>2022-07-04T09:30:09,800 | ERROR |
