If it's impossible (or unwanted) to do it internally, we'll do it by 
parsing some other BIRD outputs.

But another BGP attrubutes (med, as_path, local pref, ...), which make 
sense in BGP route selection process, already seen at "show protocols 
all" output, so may be logically more correct to add "router ID".
