Hi This is probably the same issue as this: http://comments.gmane.org/gmane.network.bird.user/4158 You could try with both 'capabilities on' and 'enable route refresh off'. Or you could try upgrading firmware on Juniper: http://permalink.gmane.org/gmane.network.bird.user/4241 -- Elen sila lumenn' omentielvo Ondrej 'Santiago' Zajicek (email: santiago@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."

You could try with both 'capabilities on' and 'enable route refresh off'. It helped, thanks!
