UPAs may not even contain the advertised locator in SIDs. That is not clearly spelled out what exactly ABRs should advertise.
I presume: a) something which was flooded in the local domain and was not being leaked AND b) something which stopped to be flooded in a local domain AND c) there is local policy specifying such range agree with Bruno’s statement “If you believe that all you need is > RFC5305/RFC5308 I guess this means that we don't need > draft-ppsenak-lsr-igp-ureach-prefix-announce” > Well at this time this is an Informational draft. But based on Bruno's comments I am worried if any node receiving something with MAX_PATH_METRIC which was not advertised before as valid and reachable prefix and did not make it into LSDB or RIB/FIB will not simply introduce a new unknown for the implementations state how to handle such prefix which may result in different interesting undefined behaviour(s). Thx, R.
