router_id or source neighbor in import/export filter for dynamic BGP peers

[Mikhail Mayorov]

Hi!

I use dynamic BGP peers in my RR. It's very simple and comfortable. 
import/export filters are same for all dynamic neighbors. How to 
determine a neighbor? Using what variables?

I will plan use filters likes that, but I can't find what I need send to 
function "getneighbortype".....

function getneighbortype(ip neighbor) -> int
  {
  case neighbor {
    1.1.1.1 : return 1; # router with big RIR
    1.1.1.2 : return 3; # router with small RIR
    else: return 0; # unknown router
    }
  }

filter fromclientrr {
  int nt = getneighbortype(*router id / src neighbor*);
  if nt = 0 then reject;
  bgp_large_community.add((0,1,nt));
  accept;
  }

filter toclientrr {
  int nt = getneighbortype(*router id / src neighbor*);
  if net.len = 0 && nt ~ [0, 3] then accept;
  if nt ~ [1] then accept;
  reject;
}
