The following changes made in this updated version:
- AS0 ROA consideration  (Tim)
- 0.0.0.0/0 (IPv4) or ::/0 (IPv6) consideration  (Keyur)
- Jeff Haas' suggestions about implementation included

URL:            https://tools.ietf.org/html/draft-sriram-sidrops-drop-invalid-policy-02   

Please let authors know about your reflections on the following wordings in the draft:

   The existence of an AS0 ROA for a prefix means that the prefix or any
   more specific prefix subsumed in it are forbidden from routing except
   when there exists a different ROA with a normal ASN for the prefix or
   the more specific prefix.  DISR policy MUST apply the following
   exception: If a route is Invalid due to an AS0 ROA, then always drop
   the route.

   Any routes for 0.0.0.0/0 (IPv4) or ::/0 (IPv6) in the routing table
   must be excluded from consideration in the DISR policy.  (Author's
   note: Think this through with help from the WG.)

Thanks.
Sriram

Title:		Origin Validation Policy Considerations for Dropping Invalid Routes

Abstract:
   Deployment of Resource Public Key Infrastructure (RPKI) and Route
   Origin Authorizations (ROAs) is expected to occur gradually over
   several or many years.  During the incremental deployment period,
   network operators would wish to have a meaningful policy for dropping
   Invalid routes.  Their goal is to balance (A) dropping Invalid routes
   so hijacked routes can be eliminated, versus (B) tolerance for
   missing or erroneously created ROAs for customer prefixes.  This
   document considers a Drop Invalid if Still Routable (DISR) policy
   that is based on these considerations.  The key principle of DISR
   policy is that an Invalid route can be dropped if a Valid or NotFound
   route exists for a subsuming less specific prefix.
