Feature Request: Bird should be able to find out the correct source address for next hop self automatically

[Dr. Christian Riede]

Hello,

with 

protocol bgp {
  local as 48175;
  import filter as12843in;
  export filter as12843out;
  enable as4 yes;
  hold time 600 ;
  keepalive time 10;
  neighbor 2A02:0788:0001:0008::1 as 12843;
  path metric 1;
  next hop self;
}

I get

bird> show route export bgp12 all
2001:67c:39c::/48  via 2001:67c:39c:8000::8000:4 on eth0 [static1 09:39] * (2000)
        Type: static unicast univ
        BGP.origin: IGP
        BGP.as_path: 48175
        BGP.next_hop: 2001:67c:39c:8002::8000:3
        BGP.local_pref: 100

After configuring the source address manually, I get the correct next hop:

protocol bgp {
  local as 48175;
  import filter as12843in;
  export filter as12843out;
  enable as4 yes;
  hold time 600 ;
  keepalive time 10;
  neighbor 2A02:0788:0001:0008::1 as 12843;
  path metric 1;
  source address 2a02:788:1:8::3;
  next hop self;
}

bird> show route export bgp12 all
2001:67c:39c::/48  via 2001:67c:39c:8000::8000:4 on eth0 [static1 09:39] * (2000)
        Type: static unicast univ
        BGP.origin: IGP
        BGP.as_path: 48175
        BGP.next_hop: 2a02:788:1:8::3
        BGP.local_pref: 100

According to the documentation, bird should be able to find out the
correct source address automatically.  But is does not ;-)

This is bird 1.3.9

Mit freundlichen Grüßen
