Hi All, 

I am facing something very strange from almost a week now. I have multiple i-bgp neighbors which are working just fine. 

# birdc show protocols 
bgp_r4 BGP      master   up     2019-01-21  Established     
bgp_r3 BGP      master   up     2019-01-21  Established   
bgp_r2 BGP      master   start  15:04:30    Active        Socket: Connection refused

There as in issue with only one of them. It did work initially but for some reason it is now down since a few days. I have tried everything in my knowledge but have failed to bring it to work again. 

Below are the configurations: 

# R-1 #
protocol bgp bgp_r1 {
        # disabled;
        debug { states, routes, filters, interfaces, events };
        router id 10.10.2.1;
        local as 65001;
        neighbor 10.10.2.2 as 65001;
        next hop self;
        direct; 
}

# R-2 #
protocol bgp bgp_r2 {
        # disabled;
        debug { states, routes, filters, interfaces, events };
        router id 10.10.2.2;
        local as 65001;
        neighbor 10.10.2.1 as 65001;
        next hop self;
        direct; 
}

Any idea what can be the possible reason behind this? 

Thanks,
