LISP ACT Values

Registration Procedure(s)

IETF Review or IESG Approval

Reference

[RFC9301]

Available Formats

CSV

Value	Action	Description	Reference
0	No-Action	The map-cache is kept alive and no packet encapsulation occurs.	[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 Mapping System.	[RFC9301]
5	Drop/Auth-Failure	A packet matching this Map-Cache entry is dropped because the Map-Request for the target EID fails an authentication check by the xTR or the Mapping System.	[RFC9301]
6-7	Unassigned
