Hi Tony，

1).  It seems that Area Proxy can not be amended to IS-IS TTZ. IS-IS TTZ abstracts a zone to a single node. This abstraction is supported by the extensions to IS-IS, and some of these extensions are not defined in Area Proxy. For example, the extensions for the edge nodes of the zone are not defined in Area Proxy.

    The details is underlined above. It says that some of the extensions in IS-IS TTZ are not defined in Area Proxy. It seems accurate if we look at the details.

Best Regards,
Huaimo

Hi Huaimo,

I feel that this is somewhat imprecise.

>From my perspective, our attempts to collaborate have been hampered by governmental regulations that are wholly out of our control. The suggestions that I’ve made for continued collaboration within the bounds of those controls have not been well received. Thus, to say that something cannot be done is overstating the case.  We have simply not been wiilling to do so, which is most unfortunate.  Who can say what could happen if we could find a way for all three proposals to collaborate?

Regards,
Tony
