I support publication of the document as an informational RFC.
Below are my comments.
Thanks,

- pg 5, line 1
What is the criteria that allow sharing the AS number? Is there a
reference?
- pg 6
"This means that every new connection will be established
obliviously (memory- less) with regards to the paths chosen
before, or chosen by other nodes."
I am not sure what "chosen by other nodes" adds. I think it
can be removed.
- pg 7
"local label 1600x" -> "local label (16000 + x).
Also because of the way loopbacks are assigned, does this mean that the
number nodes that this scheme can handle is 512? May be good to mention
why this is considered a good number.
- pg 11
"BGP Prefix Segment 16011 then directs the packet down to Node11 along
the path (Node5, Node9, Node11)."
I think it would be worth mentioning that node 9 need not appear in this
path. In general, because of the nature of clos topologies, there is no
need to have intermediate nodes between the spine and the ToR on the way
down. (If there is, it would be good to know why.)
Editorial
- some inconsistencies throughout. would be good to make them consistent.
Node1 and Node2 vs Nodes 1 and 2 vs "Node1" and "Node2"
