[RFC9301] 1 Natively-Forward The packet is not encapsulated or dropped but natively forwarded. [RFC9301] 2 Send-Map-Request The packet invokes sending a Map-Request. [RFC9301] 3 Drop/No-Reason A packet that matches this map-cache entry is dropped. An ICMP Unreachable message SHOULD be sent. [RFC9301] 4 Drop/Policy-Denied A packet matching this Map-Cache entry is dropped because the target EID is policy-denied by the xTR or the [RFC9301] Mapping System. 5 Drop/Auth-Failure A packet matching this Map-Cache entry is dropped because the Map-Request for the target EID fails an [RFC9301] authentication check by the xTR or the Mapping System. 6-7 Unassigned LISP Address Type Codes (CLOSED) Reference [RFC6830][RFC9301] Note Registry closed per [RFC9301].
