bgp : rejected by protocol

[Patrick Lamaiziere]

Hello,

I'm not sure to understand what "rejected by protocol" means.
When a (bgp) route is updated on a bgp peer, bird learns the route and
the route is then always rejected by protocol (bgp protocol).

log: 
bgp_renater: Got UPDATE
bgp_renater > added [best] 0.0.0.0/0 via 193.XX.XX.XX on ix0
bgp_renater < rejected by protocol 0.0.0.0/0 via 193.XX.XX.XX on ix0


config:
protocol static routes_renater {
        table Trenater;
        route 129.20.0.0/16 via 129.20.252.1;
	...
}

# peer BGP RENATER
protocol bgp bgp_renater from bgptemplate {
        table Trenater;
        description "RenaterV4";
        neighbor 193.XX.XX.XX as 2200;
        export filter {
                if proto != "routes_renater" then reject;
                accept;
        };
        import filter fbgp_renater_in;
}

Thanks, regards.
