Hi Robert, The draft tries to propose a lightweight isolated flooding solution capering the existing IGP multi-instance solutions. As the suggestion proposed by Acee, it should take more work. Now it focuses on ISIS firstly. Then OSPF may be taken into account depending on the research result

Gyan, To a router, having multiple servers with the same (ANYCAST) address attached to different egress routers (A-ER) is same as having multiple paths to reach the (ANYCAST) address. You are absolutely correct that there are many tools to influence the path section, such as the routing

same thing. if you want go multiple hops ZeroMQ you need forwarding already. And if you go one hop it really doesn't matter, it's just FOSE (flooding over something else ;-) -- tony On Wed, Mar 10, 2021 at 12:52 PM Robert Raszuk wrote: > > You think Kafka here? > > Nope ... I meant ZeroMQ

? Last time I looked @ it (and it's been a while) Open-R had nothing of that sort, it was basically KV playing LSDB (innovative and clever in itself). You think Kafka here? Which in turn needs underlying IGP however and is nothing but BGP problems in new clothes having looked @ their internal

Hi, Authors: I think other use case, such as 3.2 and 3.3 can also be solved by other means. Following the direction of using different routing instances to transfer such information is not one feasible way. Best Regards Aijun Wang China Telecom From: lsr-boun...@ietf.org On
