Hi, Introducing the IPv4/IPv6 extended reachability attribute flags, we are introducing some redundancy with some informations contained in Prefix-SID SubTLV, especially the N-Flag representing that the prefix belongs to the node itself. I'm not sure this is a good idea to keep both flags or if we do, we need to define the relationship between them (are they independent or not ...) N-Flag was introduced in Prefix SID SubTLV because the information was not existing at this time. Now we defined new attributes for the prefix containing this information, so the PrefixSID information is redundant and not useful anymore. For sure, we need to take care about backward compatibility as some SR codes already used N-Flag in Prefix SID for FRR. Thoughts ?
