Re: [i2rs] Kathleen Moriarty's No Objection on draft-ietf-i2rs-yang-l3-topology-08: (with COMMENT)

["Susan Hares" <[e-mail]>]

Lou and Juergen: 

 

Just to make sure I understand the pre-provisioning comment.  What you are referring to is the “when” statements in the clause below. 

 

     augment "/if:interfaces/if:interface" {

       when "if:type = 'ianaift:ethernetCsmacd'";

 

   // operational state parameters for Ethernet interfaces
     augment "/if:interfaces-state/if:interface" {
       when "if:type = 'ianaift:ethernetCsmacd'";

 

 

Thank you, 

Sue Hares

Okay, then we're on the same page -- I think some may have missed the
possibility of handling references to dynamic topology information in
config using a 'pre-provisioning' approach.

 

I would be happy to see Alex, Xufeng, Kent & Pavan articulate what this would

look like and how it would work for the base topology model, so that the WG can

consider all potentially viable options.  I'm not certain how it would function for the 

recursive nature and it does presume the separate /config and /oper-state trees in 

the data-model that were a concern (though certainly the current recommended 

approach for YANG models).
