Hello Radu,

bird[3287848]: filters, line 8: Argument 1 of RTA_SET must be of type ip,

when running with the following configuration, which works perfectly on  bird-2.16.2

 1
 2 router id from "-tun*", "*";
 3
 4 filter from_kubernetes {
 5  if ( net ~ 10.250.1.0/24 || net ~ 10.110.1.0/24  ) then {
 6    ifname = "tunl0";
 7    onlink = true;
 8    gw = from;
 9    accept;
10  }
11  reject;
12 }
.....

Which protocol originates the routes which are filtered by from_kubernetes? It looks like the from attribute is not set (which is probably another bug).

Thanks,
Maria
