I used ipv6cp-use-persistent in /etc/ppp/options files, and problem of changing link local address was solved. I can also try without ipv6cp-use-persistent, to test patch, if you there is a necessity.
But problem with convergence is still present, not always but sometimes. I enclosed again debug files, I tried few times disconnecting link, after few successful converging of link, you can see there is still a problem. The only solution was to disconnect link from other side or to restart babel process. I did not change any of parameters. ANd again thank you very much for support. I hope you dont have to much work because of my experiments :) Robert -----Original Message----- From: Juliusz Chroboczek [mailto:[EMAIL PROTECTED] Sent: Thu 7/3/2008 5:23 PM To: Robert Lukan; [email protected] Subject: Re: [Babel-users] Convergence problem > The issue is that your implementation of ppp switches link-local > addresses on every up/down event.
