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?


Hello Ondrej,
Here are the logs with= debug=A0 all { interfaces } enabled:

From that moment the error=A0 "Socket error: Ne= twork is unreachable" repeats itself until I disabled/enabled radv pro= tocol.
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 ?
