Passive BGP configuration

Hello,

where is my mistake? Static routing between 2001:db8:1::/64 and
2001:db8:1:a::/64 (configured outside of BIRD) works.

# r1 (2001:db8:1::1/64)
protocol bgp r2 {
  local as 4200000000;
  neighbor range 2001:db8:1::/50 as 4200000001;  # Never comes up
#  neighbor 2001:db8:1:a::1 as 4200000001;       # Just works...
  source address 2001:db8:1::1;
  multihop 2;
}

# r2 (2001:db8:1:a::1/64)
protocol bgp r1 {
  local as 4200000001;
  neighbor 2001:db8:1::1 as 4200000000;
  multihop 2;
}

Both systems are BIRD 2.0.7.


Regards,
  Robert
