Dear Alia,

I would need your guidance. On my side, I'm trying to help the SUPA 
people with the scope of their work.

During a SUPA call during which Sue explained the I2RS work (thanks 
again Sue), she answered a key question: any topology work should be 
based on the I2RS topology draft (draft-clemm-i2rs-yang-network-topo 
draft). This draft was called the generic topology model draft.

Discussing further with the SUPA BoF chairs, it was observed that the 
I2RS charter doesn't mention it's a generic topology model. So please 
let us know what your intention is. Is this L3 topology a generic one, 
into which all others topology-related work should plug?

The SUPA requirement is a way to express topology at several layers of 
abstraction (granularity).

Regards, Benoit
