Juergen: Your concern about "multiple overlapping objects marked config true" is reasonable, but the virtual topology is within the ephemeral I2RS state. If L2 changes state, then the ephemeral state is being changed (config true, ephemeral true)
The ephemeral I2RS state is a topic which deserves a substantial amount of discussion on the list. I will begin another topic on the mail list by tomorrow (I want to review all netconf/netmod and mail list discussions before I start). However, all the I2RS topology drafts assume the ephemeral state. I hope this helps the future part of this discussion.

Susan, multiple overlapping objects marked config true I believe are asking for trouble. Read-only is a different story but when it comes to config true objects, I am rather concerned about multiple knobs to change the same underlying resource without a clear specification how conflicts are resolved (or whether access control can be bypassed through such repeated objects). So let me revise my statement to "taking out all config true objects that are interface specific". /js -- Juergen Schoenwaelder Jacobs University Bremen gGmbH Phone: +49 421 200 3587 Campus Ring 1 | 28759 Bremen | Germany Fax: +49 421 200 3103 <http://www.jacobs-university.de/> _______________________________________________ i2rs mailing list [email protected] https://www.ietf.org/mailman/listinfo/i2rs _______________________________________________ i2rs mailing list [email protected] https://www.ietf.org/mailman/listinfo/i2rs
