Hi!
We are trying to setup an IPv6 DHCP-Server on a Cisco 878 (c870-advipservicesk9-mz.124-15.T13.bin). The clients (Windows XP) are getting two global unicast addresses (2x 2001:XXX:668::). Is this normal? We think that one address is published by the DHCP-Server and the other one is from autoconfiguration. Am I right or is there an error in the configuration?
Here is a part of the code:
-------------------------------------------------------------------

ip name-server 2001:XXX:XXXX:6::53

ipv6 unicast-routing
