Question for proper RPKI check integration in the bird v2.0.4 with Euro-IX Informational BGP communities

[Irene Lalioti]

Barry, thanks a lot, I appreciate the feedback. In the meantime, we have
altered the syntax a bit and it seems to work this snippet. (The issue
still persists with the pair errors I sent in my previous email)

filter bgp_in_AS39180_4
prefix set allnet;
{
        include "/etc/bird/prefix-lists/AS39180-v4";
        if (is_martian4()) then reject;
        if ! (net ~ allnet) then reject;
    if (roa_check(r4, net, bgp_path.last_nonaggregated ) = ROA_INVALID )
then{
        bgp_large_community.add((49624,1000,4));
        accept;
        print "Invalid ROA ", net, " for ASN ",
bgp_path.last_nonaggregated, "from AS39180" ;
    }
    if (roa_check(r4, net, bgp_path.last_nonaggregated ) = ROA_VALID ) then{
        bgp_large_community.add((49624,1000,1));
        accept;
    }
    if (roa_check(r4, net, bgp_path.last_nonaggregated ) = ROA_UNKNOWN )
then{
        bgp_large_community.add((49624,1000,2));
        accept;
    }
}

regards, Irene
