[OPNFLWPLUG-519] [GROUP-CHAINING]Deleting a child Indirect-Group from a parent All-group does not delete the parent from the config DS.

Mon, 27 Sep 2021 09:01:36 +0000

The configuration that we are trying out is an All group pointing to multiple Indirect groups.

(3)-->

{1,2}

We have tried deleting the "indirect" group type with group id = 2 which is a child of group type "all" with group id = 3.
Group id 3 also has "indirect" group type with group id - 1. The config DataStore shows group-1 and group-3.

The parent All group is should get deleted when the child indirect group is deleted .

This can be a problem during reconciliation. If the switch goes down or crashes and the controller adds a different group with group-id 2, when the switch restarts it will have a wrong set of groups.

Test steps executed :

1- Connect cpqd switch to controller.
2- Push groups using REST ( POSTMAN app ). Group-1=> type group-indirect, Group-2=> type group-indirect,Group-3=> type group-all.
3- Now delete Group 2 .
4. Group gets deleted from switch but not from config datastore.

Now if we

1.Stop the switch
2.Add a new group with same group-id but different action
3.Start the switch
4.The switch has the wrong set of groups as the parent group still points to the (old)two child ones.

Hence its a major problem during group-reconciliation
