Description (partial)

Symptoms: IPv6 DNS RADIUS attributes do not overwrite locally-configured IPv6
DNS server. The CPE gets the two locally configured DNS-servers and the two
 DNS-servers from RADIUS (four in total). 
 Conditions: The symptom is observed in a PPPoE environment. The IPv6 DNS RADIUS
 attributes sent down with a RADIUS accept packet, must overwrite the
 locally-configured IPv6 DNS server under the DHCPv6 server. This does not occur
 causing the issue.
