Brian and Shunwan: 

<chair hat on> 


Based on Alvaro’s reading of the early allocation policy, all you have to do at this point is ask the chairs. 

You have an draft.  Alvaro will approve the early allocation based on the draft. 


I hope this encourages the draft-idr-bgp-open-policy to simply ask.  I can process the request today.

Hi guys,


Section 9 of draft-ietf-idr-bgp-open-policy-06 says:


   This document defines a new optional, transitive BGP Path Attributes

   option, named "Only To Customer", assigned value <TBD3> [To be

   removed upon publication:

   parameters/bgp-parameters.xhtml#bgp-parameters-2] [RFC4271].  The

   length of this attribute is 0.


[Comment]  The length of this attribute should be 4 per the description of section 6. 

Type 35 with the name “Internal Only To Customer” has been assigned to previous version of draft-ietf-idr-bgp-open-policy. Can we simply use Type 35 for "Only To Customer" attribute, or apply a new one?


IMNSHO, apply for a new one.

(It's not like there is a danger of running out any time soon.)


Technically, the previous one had different meaning/semantics, and was assigned. 

The principal of "don't re-use, no matter what" should apply to be 100% certain no one did an early implementation that now conflicts with the new semantics.

It is the only way to be safe for absolute certain.
