The "fix" is to clear ipv6 dhcp client Dialer123 I use event manager to do this automagically for me like so:
event manager applet monitor_ipv6_dhcp event syslog pattern "DIALER-6-BIND" action 1.0 cli command "clear ipv6 dhcp client Dialer1" This reacts to an event in the log of "DIALER-6-BIND" which for me is my Dialer re-establishing its PPP session, do a clear int d123 and check your logs to verify this for you. You can view the results of event manager by: router#sh event manager history events No. Time of Event Event Type Name 1 Sat Nov 7 11:12:56 2009 syslog applet: monitor_ipv6_dhcp and of course a sh ipv6 dhcp interface d123 will show you your new lease aswell.
