Dear authors of draft-dong-teas-enhanced-vpn-control-plane,

Thanks for introducing this new draft [1] which describes a control 
plane consideration for Enhanced VPN. IMO, this document needs to 
deliver another considerations or technical notes for the way to assign 
a dedicated segment routing SID for a reserved resources on a network node.

Furthermore, as for the distributed control plane (section 3.1), why 
don't you mention the SR-policy 
(draft-ietf-spring-segment-routing-policy)? I think the SR-Policy can be 
a candidate approach for the control plane of Enhanced VPN; especially 
BGP based L3VPN (RFC4364) is utilized for the overlay of Enhanced VPN.
