Does the wireless support the IPV6 RDNSS attribute?

The wireless controllers of the V7 platform, and the version after the C5421 version will start to support the IPV6 ND RA DNS attribute for IPV6 network announcement and request DNSV6. This type of attribute is generally called RDNSS: the route announcement option mechanism defines a new neighbor discovery (ND) option RDNSS, which includes the DNS server address, and can use the existing ND announcement and request mechanism.
