Re: [Softwires] Softwire Interim Meeting, 2011 Sep. 26-27

[Ole Troan <[e-mail]>]

Naoki,

> Please don't forget SA46T-AS. SA46T-AS have IPv4 address sharing capability with SA46T extension.

agree, apologies, I missed the AS part.

remind me to ask you some questions about how you can use SA46T-AS for connecting IPv4 islands across an IPv6 network without having to assign special SA46T-AS prefixes, different from native IPv6 ones...

cheers,
Ole
