Hi. I'm using a fairly standard setup on debian wheezy with bird 1.4.0 where ospf is connected to area 0 on the wan interface and I have a stub interface on a vlan interface to the local lan. interface "eth5.2001" { cost 10; stub yes; check link yes; } When I boot the router, bird doesn't detect that the vlan interface comes up and stays in the down state. I have to restart the ospf protocol so that bird rescans the interface and start propagating connected networks. During boot kernel logs that the link becomes ready ADDRCONF(NETDEV_CHANGE): eth5.2001: link becomes ready when I remove the "check link yes" parameter, it works correctly. Is this a bug or the problem is that vlan interfaces are not supported? thanks martin
