itself until I disabled/enabled radv protocol. The dual-stack ppp session on interface ppp243 ended and after 9 sec. another session which is only ipv4 started on same interface ppp243. Radv tries to send RA on interface ppp243 which now is not v6-enabled. So is like you said. What can be done ? thx, --0015177407d460d95f04a7d14fdd Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable <br><br><div class=3D"gmail_quote">On Mon, Jul 11, 2011 at 6:27 PM, Ondrej = Zajicek <span dir=3D"ltr"><<a href=3D"mailto:santiago@crfreenet.org">san= tiago@crfreenet.org</a>></span> wrote:<br><blockquote class=3D"gmail_quo= te" style=3D"margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204= , 204); padding-left: 1ex;"> <div class=3D"im">On Mon, Jul 11, 2011 at 05:06:49PM +0300, Bogdan Besliu w= rote:<br> > =A0 =A0and the last messages repeats itself until hdd is full; or bird= 6 daemon<br> > =A0 =A0stop working.<br> > =A0 =A0it looks like the problems appear when radv tries to send RA an= d at the<br> > =A0 =A0same time ppp interface goes down.<br> ><br> > =A0 =A0any ideas ?<br> <br> </div>One possible idea is that ppp iface remains up, but its link-local<br=
