Tom:

See the charter text from http://datatracker.ietf.org/wg/i2rs/charter/

o The ability to extract information about topology from the network.  Injection and creation of topology will not be considered as a work item. Such topology-related models will be based on a generic  topology model to support multiple uses; the generic topology model should support topology extension for non-I2RS uses.

The L2 draft is a Protocol independent an extension of the generic protocol-independent topology module at layer 2.  Please see  <http://datatracker.ietf.org/doc/draft-clemm-i2rs-yang-network-topo/> draft-clemm-i2rs-yang-network-topo-04 for details on generic model that points to multiple layers. 

The L3 and L2 drafts provide layers of the protocol-independent.  The L1 Topology draft and Service topology drafts need addition work to be aligned with the TEAS WG and other service topology WGs (L3SM, SFC, and SUPA BOF).  Drafts at the L1 layer and Service layer are still within the protocol independent topology. 

The WG Adoption calls (L3 topology and L2 topology) are based on this understanding of the I2RS charter

            Is this currently in the charter or does the charter need to be extended 

to allow for non-RIB related topology models to be included in i2rs? As I recall,

this is why we didn't do any L1 topology for optical networks, which was

something one particular operator requested at the time but was pushed 

back based on that not being in the charter.  At the time, the message was

that we should only focus on l3 topology (i.e.: routing/RIB-related).

o The ability to extract information about topology from the network.  
Injection and creation of topology will not be considered as a work 
item. Such topology-related models will be based on a generic 
topology model to support multiple uses; the generic topology model 
should support topology extension for non-I2RS uses.
o Other use cases may be adopted by the working group only through 
rechartering.

- Yang Data Models consistent with the use cases. Such documents 
should include an information overview. The existing WG draft - 
draft-ietf-i2rs-rib-info-model - that is just an informational model 
can be completed or extended with the associated YANG data model.

Please indicate in your comments “support” or “no support” and discuss how this draft will allow I2RS client-agent pairs to query information about L2 topology.  The draft can be found at:
