Questions on draft-ietf-l3vpn-vpn-vr-02.txt

["Vishal Sharma" <v.sharma at ieee.org>]

Hi Paul and co-authors,

Could you please clarify a few things in the latest version of this
document:

- Sec. 2.5.1. states that the 
"The routing 
   protocol between the CE and the VR running on the PE MAY be 
   independent of the PE-to-PE routing. "

Why is this a MAY? Would one not want the routing protocol
between the CE and its corresponding VR on the PE to be always
independent of the PE-to-PE routing protocol?
When is there a case when these protocols are not independent?

- Sec. 2.5.3, I assume when "CE-to-PE routing" is used, it actually
means "routing between the CE and the VR (on the PE to which the CE
is attached) corresponding to the VPN of which the CE is a part"
Is this correct?

If so, it might be useful for the document to clarify somewhere
up front that when "CE-to-PE" routing is used, this is what is
implied.
 
- Sec. 2.5.3, "VRs 
   of customer VPNs MAY use the backbone VR for routing across the 
   backbone." probably needs to say "the backbone VR network".

Thanks,
-Vishal
