[c-nsp] OSPFv3 Multiple Address Families Support in IOS

[Christopher Werny]

Hi Darren,

Cisco implemented finally the OSPFv3 Authentication Trailer (RFC 7166) beginning with 15.4S/T/M. I was able to configure it without a problem on a 2921 running 15.4(3)M with ipbase license in our lab.

Best,
Christopher

There was an issue, at least a year or two ago, when it came to authentication on ospfv3. 

Ospfv3 doesn't have built in authentication, rather it relies on ipv6 IPSec. That's all fine and good until you realise you need the security license on ios in order to use IPSec. So you cannot authenticate your peers with v3 out the box on unlicensed ios.

I would need to check if this has changed though
