Correct way to advertise network in BIRD 2.x

[Laura Smith]

Hi,

I am unfortunatley finding the docs a little terse in terms of lack of 
real-life examples.

I have a simple question, how do I advertise networks to my peers ?  I am 
guessing the syntax below is not correct because I see error messages such as

"Apr 27 11:08:53 vpw bird: KRT: Received route 192.0.2.224/28 with strange 
next-hop 198.51.100.33" in my logs.

2a01:db8:a1d:1e11::1111 / 198.51.100.33 is the IP of the interface facing the 
upstream BGP peer.

protocol static {
  ipv4;
  route 192.0.2.224/28 via 198.51.100.33;
}

protocol static {
  ipv6;
  route 2a01:db8:6a66::/48 via 2a01:db8:a1d:1e11::1111;
}

filter out_filter {
  if net ~ 2a01:db8:6a66::/48 then accept;
  if net ~ 192.0.2.224/28 then accept;
  else reject;
}

protocol bgp v4n1 {
    local as 65200;
    source address 198.51.100.33;
    neighbor 198.51.100.250 as 64515;
    med metric on;
    default bgp_med 0;
  ipv4 {
    import all;
    export filter out_filter;
    graceful restart on;
  };
}

protocol bgp v6n1 {
    local as 65200;
    source address 2a01:db8:a1d:1e11::1111;
    neighbor 2a01:db8:a1d:1e11::2222 as 64515;
    med metric on;
    default bgp_med 0;
  ipv6 {
    import all;
    export filter out_filter;
    graceful restart on;
  };
}
