Bird 1.4.5 add-path crash

[Alexandre Corso]

Hello,

We have the same problem with some of our clients. The problem with "add path" doesn’t look like to come from Bird 1.5.0 but with the connected router.

In our configuration we have this template.

template bgp PEERS {
  local as MyASN;
  import all;
  export all;
  rs client;
  passive on;
  add paths tx;
}

Bird Version :
BIRD 1.5.0 ready.

The problem with BIRD 1.5.0 is the "enhanced-refresh”. That leads to "Received: Required capability missing”. You can try to remove this capability with this argument on you bgp configuration : enable route refresh off.

Best regards,
