The issue described in http://forum.mikrotik.com/t/bgp-sessions-close-when-another-session-to-the-same-ip-closes/175478/1 has become much worse in 7.16
(BGP sessions close when another session closes)
In previous versions it appeared to affect only BGP sessions with the same local IP, now it sometimes affects ALL sessions…
When a peer on L2TP/IPsec disconnects because their public IP has changed and they re-establish the L2TP/IPsec session, I have observed several times that all BGP sessions (15 total) go to Idle state and have to re-connect.
Nobody else noticed that?
