Hi, Rolf: Would you like to describe in detail the scenario that you use such proposal in your SRv6 based production network?
1) The simplified topology? 2) How many times in your network emerge the prefixes unreachable problems within one year? 3) What’s the receiver’s action before and after it receives the unreachable notification? 4) How many nodes in the network are aware of the notification? 5) How many ABRs are deployed in your scenarios? Do all of them send the unreachable notifications? 6) What’s the comprised content of unreachable notification messages? Knowing the above information can authenticate your declaration.
