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,

Alexandre Corso

Hello,

I'm seeing Bird 1.4.5 crash with a segmentation fault when receiving
routes from a peer with add-path enabled.

Hello

There is one known bug in add-path in BIRD 1.4.5 that is already fixed
in 1.5.0, could you try 1.5.0?

With 1.5.0 the session does not establish:

bird: Started
bird: bgp1: Received: Required capability missing
