=E2=80=8BIt will work if you 'help' bird to know the source address to use =
(source
address) into the BGP protocol.
Here is the extract of my bird BGP configuration file (no setkey.conf
needed):

protocol bgp R4inet4 {
        local as myas;
        # Bird creates IPSEC SAD entry automatically but it need to
know the source IP address
        # Otherwise it will use the wrong 0.0.0.0 IP as source
        source address 10.0.2.3;
        neighbor 10.0.2.4 as 200;
        password "abigpassword";
        ipv4 {
            import all;
            export all;
            next hop self;
        };
}
