Can the authors give more explanation on the following description in
https://datatracker.ietf.org/doc/html/draft-ietf-idr-bgp-open-policy-10#sect
ion-8:

 

There are peering relationships that are 'complex', i.e., both

   parties are intentionally sending prefixes received from each other

   to their non-transit peers and/or transit providers.  If multiple BGP

   peerings can segregate the 'complex' parts of the relationship, the

   complex peering roles can be segregated into different normal BGP

   sessions, and BGP Roles MUST be used on each of the resulting normal

   (non-complex) BGP sessions.

 

Some figures or more detailed explanations will be helpful to get the
description of “complex”.  Is there any situation that the multiple BGP
peering can’t be segregated?

 

 

Best Regards

主题: [Idr] WG LC for draft-ietf-idr-bgp-open-policy-10.txt (6/4 to 6/18)(.

 

This begins a 2 week WG LC for draft-ietf-idr-bgp-open-policy-10.txt

>From 6/4 to 6/18/2020.  

 

There are 3 implementations:   BIRD (1.76, 2.05) , FRR, and Mikrotik. 

The BIRD and FRR implementations interoperate. 

I do not have details on Mikrotik.  

 

Details on the  interoperability are on the following IDR wiki page: 

https://trac.ietf.org/trac/idr/wiki/draft-ietf-idr-bgp-open-policy

 

Only one  error handling issues exists on the ability of BIRD 

to send Role Mismatch (Open Error (2), subcode 8).  

Another protocol was assigned to subcode 8.  

 

Please comment on the following questions: 

1) Is this specification ready for publication? 

2) Are there deployments where this BGP protocol extension is valuable? 

3) Do you believe the error code handling is ready for publication? 

 

The shepherd for this draft is Susan Hares.  

During the WG LC, the shepherd’s report will be sent.
