Hi,

following scenario:

Gateway (running radvd) [00:50:BF:06:B4:F5] and a client with one interface (forwarding disabled) [00:e0:18:90:92:05].

Client boots, neigborhood detection works and take the given prefix from radvd to assign a global address for the one and only interface.

14:00:54.475785 :: > ff02::1:ff90:9205: icmp6: neighbor sol: who has fe80::2e0:18ff:fe90:9205
14:00:58.476075 fe80::2e0:18ff:fe90:9205 > ff02::2: icmp6: router solicitation
14:00:58.502708 fe80::250:bfff:fe06:b4f5 > ff02::1: icmp6: router advertisement
14:00:58.996090 :: > ff02::1:ff90:9205: icmp6: neighbor sol: who has 3ffe:400:100:f101:2e0:18ff:fe90:9205

Ok, 3ffe:400:100:f101:2e0:18ff:fe90:9205 was added on client interface, routing entries are also added.


But if I switch down and up the network (completly or only interface), the mechanism won't work:

14:01:22.037731 :: > ff02::1:ff90:9205: icmp6: neighbor sol: who has fe80::2e0:18ff:fe90:9205
14:01:26.038013 fe80::2e0:18ff:fe90:9205 > ff02::2: icmp6: router solicitation
14:01:26.142629 fe80::250:bfff:fe06:b4f5 > ff02::1: icmp6: router advertisement

the final "neighbor sol" is missing, neither address nor routing is well configured for global usage. Looks like the client do not accept the advertisement. But "accept_ra" is unchanged, also forwarding on client side - still disabled.

Is there a hidden switch somewhere or something else like a retrigger?

Happens with 2.2.17 and 2.4.0.

Can someone reproduce this? Any hints?

TIA,
        Peter
