Hi Sasha, If you read the beginning of even yang, it has a common leaf which indicating it is IR or P2MP. But it is globally not per EVI. So actually I also have a comment here I may forgot to mention in previous email is that this common leaf should be per EVI basis not globally. If this info should be included in route leaf, the common leaf actually can be deleted I believe. So basically I support what you said.
Hi author, Thanks for the new version which fixes a lot. But I still have some concerns on the current version. I will try put major ones down later. Here just quick query on the usage of counter32 in statistics, isn't it very likely to get full in short time? If you check interface-yang it always use counter64. If I calculate correctly, with 1mbps traffic counter32 will rotate in about 1 hour. Or I miss sth? Thanks in advance.
