Himanshu: Just to make sure I understand your comment, you do not feel an I2RS WG draft on topology should include a protocol independent virtual topology at Layer 2. I will bring this comment to the attention of the Routing AD in charge of the I2RS work.
The L2VPN, BESS, IEEE, PALS document are considered protocol specific topologies - so these are not the same thing (according to Alia Atlas, AD). The I2RS Working group is not charter to work on these protocol-specific modules. I do agree that TEAS and I2RS carefully need to work through on the Traffic Engineering topologies and logical topologies. I am monitoring the design teams so that we coordinate this portion of the TEAS/I2RS work.

This work does not seem to applicable to I2RS WG. At best, it is related to L2VPN WG, now, PALS and BESS. And in addition, there are other SDOs that are working on this as well. It would be difficult to unwind the overlap. /himanshu -----Original Message----- From: i2rs [mailto:[email protected]] On Behalf Of Susan Hares Sent: Monday, April 06, 2015 3:57 PM To: 'Thomas D.

Thank you for that input. The I2RS L2 protocol topology is the protocol independent topology. Just as Alexander Clemm points out that the L3 topology may be a virtual composite of either the static setting or a combination of the protocol specific topologies, the L2 topology is a virtual composite of the lower L2 topologies.

There has been indication at least, that the IEEE was going to embark on this work to reflect the L2/bridge MIB work that went on there. But as you say, there has been no official liaison to the IETF on this.
