Oh, it certainly is (per the IETF IPR rules).


which rfcs? I can find a draft in softwire:
   http://tools.ietf.org/html/draft-mdt-softwire-map-translation-01

and a reference to this in wikipedia:
  http://en.wikipedia.org/wiki/IPv6_transition_mechanisms#MAP

which says: "...(MAP) is a Cisco IPv6 transition proposal..."

so.. err, we won't see this in juniper gear since:
  1) not a standard
  2) encumbered by IPR issues

weee!


Thanks for the clarity, Chuck.

Cheers,
Rajiv

I think he means patent encumbered.

Chris,

UmmmÅ  you mean the IPv6 and IPv4 inter-dependency when you say IP
encumbered?

If so, the answer is Yes. v6 addressing doesn't need to change to
accommodate this IPv4 A+P encoding.


Cheers,
Rajiv

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.





glad it's cross platform... is it also IP encumbered so it'll remain
just
as 'cross platform' ?
