Re: IPv6: 2.4.2/3 autoconfiguration sometimes didn't work

[Bill Robertson <bill.robertson@xxxxxx>]

I have a 2 host network with a 2.2.19 based router running radvd 0.6.2 (not 
p11) and a 2.2.19 based client and am having the same problem as 
Peter.  Most of the time the client doesn't autoconfigure itself to the 
site local address being provided in the router advertisements.

I tried both "/etc/rc.d/init.d/network restart" and Peter's suggestion of 
"ifconfig eth0 down" followed about 60 seconds later by "ifconfig eth0 up". 
Neither seems to work.

When autoconfigure fails I see:

08:05:59.643602 fe80::210:5aff:fec8:ca2e > ff02::2: icmp6: router solicitation
08:05:59.692754 fe80::210:5aff:fe9e:2e7a > ff02::1: icmp6: router advertisement
08:06:06.662744 fe80::210:5aff:fe9e:2e7a > ff02::1: icmp6: router advertisement

when it works I see:

08:08:12.359210 fe80::210:5aff:fec8:ca2e > ff02::2: icmp6: router solicitation
08:08:12.622758 fe80::210:5aff:fe9e:2e7a > ff02::1: icmp6: router advertisement

08:08:12.623064 fe80::210:5aff:fec8:ca2e > fe80::210:5aff:fe9e:2e7a: icmp6:

08:08:12.623093 fe80::210:5aff:fe9e:2e7a > fe80::210:5aff:fec8:ca2e: icmp6:

08:08:13.259079 :: > ff02::1:ffc8:ca2e: icmp6: neighbor sol: who has cn.crc.ca
08:08:19.952751 fe80::210:5aff:fe9e:2e7a > ff02::1: icmp6: router advertisement

I can usually force address autoconfiguration to work by rebooting the 
client rather than doing a network restart.

Any suggestions would be appreciated.

Thanks.
