Bird within netns (no OS routing table injection with BGP)

Hi all, I'm trying to use bird within netns with something like "ip netns exec foo bird". I can see received routes in "show route" but the injection in the OS routing table is not done. Strangely, static routes are correctly injected. With BGP routes I have no particulary debug messages, except "Netlink: Invalid argument" with bird6. Using Quagga, routes are correctly injected inside netns. Any idea about that problem? * Bird 1.3.7-1 * GNU/Linux (Debian Wheezy) Regards, ju.
