[c-nsp] Cisco and RFC 6106 (RDNS in IPv6 RAs)

[Christopher Werny]

Hi everyone,

I haven't seen any "official" announcement that RDNS option in RAs is finally supported in Cisco IOS, and my google/fn-fu did not result in any success (but this could be a typical layer 8 problem ;)). 
However, I stumpeld over an Cisco IOS IPv6 Command Reference Guide which included the command " ipv6 nd ra dns server" that achieves what I am looking for, but I couldn't find any  information on which Devices/IOS trains this command is supported. 

The Reference Guide can be found here: 

http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipv6/command/ipv6-cr-book/ipv6-i3.html#wp3800310030

Does anyone know on which trains/devices this command is supported? or have some general pointers in regards to RFC 6106 support in Cisco IOS?

Thanks for your time !

Cheers,
Chris
