Hello, I'm testing bird 1.3.1 protocol radv . The configuration is: router-id 1.1.1.1; protocol device { scan time 10; }; protocol radv { interface "ppp*" prefix 2001:1111:1111::/64 { autonomous on; }; }; most of the time it works ok but from time to time it happens something like this: un 17 18:19:41 ppp-test pppd[8032]: No response to 3 echo-requests Jun 17 18:19:41 ppp-test pppd[8032]: Serial link appears to be disconnected.

One possible idea is that ppp iface remains up, but its link-local address was removed, is this possible? (or at least BIRD thinks it is still up). Could you enable debug messages using "debug all { interfaces }" command? -- 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."

Hello Ondrej, Here are the logs with debug all { interfaces } enabled:
