Hi Huaimo,


> 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.

Apparently, we have very different understandings of the words “amended to”.

And so it goes.

Tony
