Drift and Reconcile (DRC) and Idempotency for IP Prefix List Configuration

The following table captures the various attributes of IP prefix list for which DRC and idempotency is supported.

A drift is identified if any of the fields are modified through SLX, CLI or other management tools.
A reconcile operation pushes the intended configuration to SLX, so bringing the SLX configuration in sync with EFA.


Field	Identify Drift	Reconcile config	Idempotency	Comments
IPv4 prefix list rule is deleted.	Yes	Yes	No	Deleted rule will be reconciled.
IPv4 prefix list is deleted.	Yes	Yes	No	Deleted prefix list along with all rules associated with it will be reconciled.
IPv4 prefix list rule created OOB. Different rules exist with same prefix list name in EFA.	No	No	NA
IPv4 prefix-list rule created OOB. Different rules exist with same prefix-list name and same sequence number in EFA.	Yes	Yes	NA	Prefix list rule will be reconciled to be in sync with EFA.
Create a IPv4 prefix list OOB with a prefix list name not matching any of EFA created entries.	No	No	NA	These are treated as out of band entries and EFA will not perform DRC.
