BGP doesn't comming up



  • Hi!
    I have a problem with BGP at Juniper.
    After losing connection with bgp peer (not Juniper), Juniper does not coming up, after resume ping with peer.

    debug messages.:
    Jun  9 14:25:11.781177 bgp_hold_timeout:3576: NOTIFICATION sent to  (External AS 😞 code 4 (Hold Timer Expired Error), Reason: holdtime expired for , socket buffer sndcc: 57 rcvcc: 0 TCP sta
    te: 4, snd_una: 3271657324 snd_nxt: 3271657381 snd_wnd: 15833 rcv_nxt: 1996526507 rcv_adv: 1996542891, hold timer 0

    and then

    old state Idle event Start new state Active
    old state Active event ConnectRetry new state Connect
    socket 34 Socket is not connected
    old state Connect event OpenFail new state Idle

    and so on. State max Connect, and restarting bgp connecting.
    After reboot Juniper, it works about 24h, and then again lose ping and lose bgp without resuming.



  • What is the router ?  What is the remote end ?  Do you have any route flapping during this 24h duration ?
