Hi,Jakob:

 

Considering the communities is used mainly for the tag of BGP routes. 

And as also mentioned in your draft, that there are only about 22 well-known
communites have been used so far. Then what’s the necessary to
define/reserve the well-known large communities?

Why the current well-known
communities(https://www.iana.org/assignments/bgp-well-known-communities/bgp-
well-known-communities.xhtml#bgp-well-known-communities-1) can’t be used to
accommodate the requirements, which is not stated in the draft?

 

And, after reading the current version of the draft, some confusions are
raised:

1.     Where is the “type” filed, that you mentioned in
https://datatracker.ietf.org/doc/html/draft-heitz-idr-wklc-02#section-4, are
you referring the “WKLC ID” field in your encoding?

2.     The length of LC is 12 octets, as defined in
https://datatracker.ietf.org/doc/html/rfc8092, why you just use 10 octets,
and want also to encourage the user to follow the canonical representation
of RFC8092?

3.     From my understanding, your draft just want to reserve some 4 bytes
AS range for the “Global Administrator” part of the large community, is
that right? If so, what’s necessary to divide it into three parts?

 

 

Best Regards

Subject: [Idr] Adoption call for draft-heitz-idr-wklc-02 (3/9 to 3/23)

 

This begins a WG Adoption call for draft-heitz-idr-wklc-02.txt. 

 

https://datatracker.ietf.org/doc/draft-heitz-idr-wklc/

 

In your review of this draft, please consider: 

 

1) Should IDR standardize a set of “well known large communities”? 

2) Will the transitivity field help these well know large communities?

3) Is this document ready for adoption? 

 

I’ve not received Sriram’s IPR statement.  If this statement is not
received within 1 week, this WG adoption call will pause waiting for that
statement. 

 

Cheers, Susan Hares
