Hi, maybe someone can help or has experience on this. During review we have found BGP session without authentication. We now need to add this part to the existing session.
Is there any process to follow when adding authentication to an existing BPG neighbor session? Means can the authentication be added “on the fly” from both ends while the BGP is still being active? Or should BGP neighbor be deactivated for the change? Of course, downtime has to be as small as possible
Thanks & Best regards, Chris
