I've put up some monitoring to try to determine when the route is lost, but why would it be lost at all??
That would depend on where the problem is. Fire up Wireshark, to ensure the RAs are being transmitted periodically.
They are, radvd is working just fine. Has been for years. What's new is that I'm also letting radvd do the default route.
Just in case, I did check. RAs are being transmitted just fine. The presence of the default route on a Nanopi seems to suggest RAs are also being received, but I've checked that too: nano1:~ # tcpdump -n -i wlan0 ip6[40]==133 or ip6[40]==134 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on wlan0, link-type EN10MB (Ethernet), capture size 262144 bytes 19:12:27.183650 IP6 fe80::1 > fe80::96a1:a2ff:fea3:ba7a: ICMP6, router advertisement, length 136 19:12:58.946961 IP6 fe80::1 > fe80::96a1:a2ff:fea3:ba7a: ICMP6, router advertisement, length 136 nano2:~ # tcpdump -n -i wlan0 ip6[40]==133 or ip6[40]==134 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on wlan0, link-type EN10MB (Ethernet), capture size 262144 bytes 19:12:27.191338 IP6 fe80::1 > fe80::96a1:a2ff:fea4:2446: ICMP6, router advertisement, length 136 19:12:58.954853 IP6 fe80::1 > fe80::96a1:a2ff:fea4:2446: ICMP6, router advertisement, length 136 -- Per Jessen, Zürich (13.4°C) http://www.hostsuisse.com/ - virtual servers, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
