Dear all,

My analysis is that the mechanism described in the draft is a local 
load-balancing optimization, which doesn't influence the bits on the wire.

Note that Curtis had a similar concern during the OPSAWG meeting (see 
the minutes 
<http://www.ietf.org/proceedings/86/minutes/minutes-86-opsawg>),

    Curtis Villamizar: Looks like implementation details, not operational issues.
    Not appropriate here, even as an Informational RFC.  Also has concerns with
    specific approach, which requires configuration.

Therefore, I don't believe that this draft is appropriate for the WG.

Regards, Benoit (as a contributor)
