Hello guys,
Anyone got maybe VPS with BGP and BIRD in vps247.com ?
They just setup my BGP session but got strange problem my config looks like:

    router id 85.204.XXX,XXX;
    # debug protocols all;
    protocol device {
    scan time 15;
    }

    protocol static {
            route 2a04:9dc0:XXX/128 via "eth0";
            include "via.conf";
    }

    protocol kernel {
            device routes;
            import none;
            scan time 25;
            persist;
            export filter {
            include "kernel-export.conf";
            };
    }

    protocol bgp Romania
    {
        description "Romania link local";
        local as XXXXX;
        source address 2a04:9dc0:XXXX;
        graceful restart on;
        default bgp_local_pref 200;
        multihop 2;
        neighbor 2a04:9dc0:XXXX as 9009;
        import filter {
        include "export.conf";
        };
        export filter {
        include "prefix.conf";
    };
    }

And in logs got it all the time:
        Aug  8 16:08:26 bgp bird6: Romania: Error: Hold timer expired
        Aug  8 16:10:32 bgp bird6: Romania: Error: Hold timer expired
        Aug  8 16:13:48 bgp bird6: Romania: Error: Hold timer expired


The most funny session is established:
    [email protected]:~# birdc6 show proto
    BIRD 1.6.3 ready.
    name     proto    table    state  since       info
    device1  Device   master   up     14:41:18
    static1  Static   master   up     14:41:18
    kernel1  Kernel   master   up     14:41:18
    Romania  BGP      master   up     16:12:16    Established

and after ~60-120 sec:
    [email protected]:~# birdc6 show proto
    BIRD 1.6.3 ready.
    name     proto    table    state  since       info
    device1  Device   master   up     14:41:17
    static1  Static   master   up     14:41:17
    kernel1  Kernel   master   up     14:41:17
    Romania  BGP      master   start  16:13:49    Idle          BGP Error: Hold timer expired

    From what ive briefly tested i can see that each time your bgp session comes up i lose the ability to ping your server.
    I could be mistaken as im not all familiar with bird but to me that would indicate you are screwing with the route to the peer ip with all the routes you are exporting back for some reason.

    You could try changing your static route to use the gateway "2a04:9dc0:0:22::1" instead of eth0

  • Venatha thanks m8 i think i find where is problem! :-)
    nice routing to 2a04:9dc0::/29 they send me....
    that`s why i lose connection....
