CGN-like box. Yes, it's stateless. Doesn't matter, I still need to flow traffic through a dedicated box because MAP won't be implemented in my regular routers (if you know otherwise, please speak up).
Yes, MAP (T-Translation or E-Encap mode) is implemented on two regular routers that I know of - ASR9K and ASR1K. Without that, you are right that MAP wouldn't have been as beneficial as claimed.
It's still NAT.
Yes, assuming MAP-T. No, assuming, MAP-E Cheers, Rajiv -----Original Message----- From: Mikael Abrahamsson <swmike () swm pp se> Organization: People's Front Against WWW Date: Monday, April 8, 2013 6:01 AM To: Rajiv Asati <rajiva () cisco com> Cc: nanog list <nanog () nanog org> Subject: Re: Verizon DSL moving to CGN

Doesn't matter, I still need to flow traffic through a dedicated box because MAP won't be implemented in my regular routers (if you know otherwise, please speak up).MAP is all about stateless (NAT64 of Encapsulation) and IPv6 enabled access. MAP makes much more sense in any SP network having its internet customers do IPv4 address sharing and embrace IPv6.It's still NAT. -- Mikael Abrahamsson email: swmike () swm pp se
