Hi Himanshu, Thanks for your comments.
Regarding the relationship between the L2 topology model and L2VPN model, currently this draft treats L2VPN as one approach of building particular connectivity in a L2 topology, and part or all of a L2 topology can also be established using other l2 technologies, e.g. Ethernet, TRILL, L2 overlay etc. Thus in my view the L2VPN model and this L2 topology model are complementary work. Of course we would like to discuss and coordinate with the L2VPN model design team in details of the model. As for other SDOs working on this, could you provide more information so that we could see whether they are also complementary or there is some overlap? Thanks.
