Re: [Idr] I-D Action: draft-ietf-idr-error-handling-03.txt

Hi, folks:

The revised version includes the following changes:

     o specify local repair for only the "Optional bit" and "Transitive" 
bit in the Attribute Flags
     o use treat-as-withdraw for missing mandatory attributes
     o reset session for duplicate MP_REACH or MP_UNRAECH
     o specify precedence for error handling actions: session reset, 
treat-as-withdraw, attribute discard
     o cover all attributes specified in the base spec, community, 
ext-community (including
        the ipv6 address based ext-community)
     o reference RFC4760 (instead of the rfc4760bis) to avoid circular 
dependencies

Please note that:

     o The MP_REACH and MP_UNREACH will be covered in a re-spin of the 
existing MP extension draft.
     o The RR related attributes will be covered by a RR re-spin.

Regards,   -- Enke
