Hi Authors, Just following up about my 2 questions during the PCE WG session about https://datatracker.ietf.org/doc/html/draft-ietf-pce-pcep-extension-native-ip-14. Question 1: Is every prefix going to be advertised (via the RR) to every node in the native-ip domain, even if those nodes are never on-path for that prefix? If my understanding is correct, the "BGP peer nodes" (R1 & R7 in Figure 4) would receive the PPA (Prefixes) and would inject these prefixes into the RR. The RR would then flood these prefixes (as regular BGP IP routes) to every single node in the domain (R2, R4, R5, R6) with the next-hop being set to R1 or R7. Please let me know if my understanding is correct or am I missing something. So even though R5 and R6 in this example are off-path, they would receive the prefix route from the RR? Question 2: Have you thought about ECMP/UCMP (Equal/Unequal Cost Multipath)? How would you implement it in your protocol? Thanks, Mike.
