BIRD

BIRD e` un demone di routing multi protocollo.

BGP route reflector client

Questo è il mio /etc/bird.conf, il demone BGP è sullo stesso host a cui è assegnata la subnet pubblica annunciata.

# This pseudo-protocol performs synchronization between BIRD's routing
# tables and the kernel.
protocol kernel {
        scan time 20;   # Scan kernel routing table every 20 seconds
        export filter {
                krt_prefsrc = 176.62.53.27; # Set SRC for routes added by BIRD
                accept;
        };
}

# This pseudo-protocol watches all interface up/down events.
protocol device {
        scan time 10;           # Scan interfaces every 10 seconds
}

# Learn routes from specified interface
protocol direct {
        interface "ninux-peering-vpn"; 
}

filter ninux_bgp_export_filter { # Announce (only) our public subnet
        if ( net = 176.62.53.27/32 ) then {
                accept;
        } else {
                reject;
        }
}

protocol bgp {
        local 10.6.6.10 as 197835; # My BGP
        neighbor 10.6.6.1 as 197835;
        import all;
        export filter ninux_bgp_export_filter;
}
