My comment at the mic was based on the verbal description of the slide. What I see in the draft text is different:

5.4.  Error Handling at Peers

   A route sent by a validating BGP speaker SHOULD only contain none or
   one EBGP Prefix Origin Validation State Large Community.

   A peer receiving a route from a validating BGP speaker containing
   more than one EBGP Prefix Origin Validation State Large Community
   SHOULD only consider the largest value (as described in Table 1) in
   the validation result field and disregard the other values.  Values
   larger than two in the validation result field MUST be disregarded.

This is different from what was described verbally. The written version seems fine to me. So, I would like to withdraw my comment.

I do suggest changing both SHOULD to MUST unless you can think of a use case for doing differently; if you can I suggest adding a MAY clause to describe the exception case.

Thanks,

—John
