Just looked at it. flood_router26 just emits pretty high values for
RetransTime:

21:05:52.050159 IP6 (hlim 255, next-header ICMPv6 (58) payload length: 192) fe80::c:2a47:1360:1101 > ff02::1: [icmp6 sum ok] ICMP6, router advertisement, length 192
        hop limit 255, Flags [none], pref high, router lifetime 65535s, reachable time 16384000ms, retrans time 1966080ms
          mtu option (5), length 8 (1):  1500
            0x0000:  0000 0000 05dc

We are completly in spec here. Just DAD needs a lot of time to finish.

Greetings,

  Hannes
