Cisco IOS Issues with DHCP PD??

Anyone else having issues with DHCPv6 on the Cisco IOS after about 3 months? It will drop v6 and I have to do a {clear ipv6 dhcp client GigabitEthernet0/0} to get it back.. I wrote a script to check for v6 down on my linux box and fix it when it is gone.. Example below: NetDogRT01#sh ipv6 int brGi

I haven't tried other routers but I am tring a EdgeMAX router now.. no logs.. Version 15.1(4)M7.. ipv6 unicast-routingipv6 cefinterface GigabitEthernet0/0 ipv6 address dhcp ipv6 enable ipv6 nd dad attempts 0 ipv6 nd autoconfig default-route ipv6 dhc

is there any thing needed on the customer side to request a ipv6 pd larger than /64?

I am needing to start assigning a couple /64's to my vm servers so that the traffic there is on its own network as well as for ddns updates. Is there any thing special that needs to be done so that I can start getting the larger address space delegated?

Biz customers get a /56, what are you tring to do? What is your setup like?
