bird bgp peer problems

[Kai]

Hello!

I habe severe problems to understand birds behaviour regarding some
peers. Two peers now carry debug parameters to analyse what's going on.
Here is one example with config excerpt and debug output from syslog.

Why is the incoming connection from the peer rejected?

What does "Bad peer AS" mean in this context? Does the peer try to
identify itself with _my_ ASN? Or does it expect me to be 65036 (what
would be correct!)?

---------------------------
protocol bgp Oldenburg1_wi from bgp_ic_wi {
    neighbor 10.207.0.27 as 65513;
    debug { states,interfaces,events };
};
# with my ASN defined to be 65036 in the template bgp_ic_wi:
template bgp bgp_ic_wi {
    local wi_addr_ic as 65036;
    router id 10.207.0.56;
    table ic_wi;
    import where (is_freifunk_dn42() && !is_wimz_self_nets());
    export where (is_wi_self_net() || (source = RTS_BGP));
    direct;
};
