Aijun – The fact that you have acknowledged the limitations pointed out by others (notably Peter) is a good thing – but it doesn’t alter the fact that what you have proposed cannot be trusted. Routers outside of an area have no way of knowing whether the area in question has unnumbered links

Hi, Les: Thanks for your comments. After the previous discussion within WG list, I had changed the description about the inter-area topology retrieval scenario, which is the original source of this draft that is different from RFC7794. We point out such use case can be applied where each

I think we are in sync, i.e. without this draft there is no use-case for node T1 to send an AS-scoped router info LSA without being ASBR. Please correct if you know of an existing use-case. Thx, Dirk On 2/18/2019 15:01, Peter Psenak wrote: Hi Dirk, On 18/02/2019 14:47 , Goethals, Dirk (Nokia -

To the extent that the draft defines functionality equivalent to that defined in IS-IS RFC 7794 – specifically a means to advertise the source router-id of a given advertisement – it defines a necessary and useful extension to the OSPF protocol – and I support that work. However, in its
