Hi Jie and Ketan，
Thank you both for the good discussion. Yes, the intent of the document aligns completely with Ketan39s opinion. Sorry for the confusion caused by the use-case description in the document sec2.2, and we will calrify this part in the next version.

You are right, that the draft should clarify this. Moreover, the use-case description of flex-algo in section 2.2 is misleading - it can be achieved using this feature only if the flex-algo definition is using some metric type other than IGP metric. The authors can correct my understanding.

It is a useful feature in general to exclude some of the links from SPF computation. I also have some comments for the authors to consider, they can be solved after the adoption. 1. I’m not sure the purpose is to advertise an unreachable link in OSPF, from the use cases in the draft, the link is still reachable and can be used for some services, just it needs be excluded from normal SPF calculation. If this is correct, it is better the title of the draft and the name of the new capability Flag need to be updated to reflect this. 2. In the Flex-Algo use case, if the metric of a link is set to MaxLinkMetric (0xFFFF) to exclude it from normal SPF computation, while a Flex-Algo is defined to use the same metric type for path calculation, will it cause the link also be excluded from the Flex-Algo path computation? If not, will metric value 0xFFFF be used in the Flex-Algo computation? In other word, the interaction between this new feature and Flex-Algo needs to be further elaborated.
