Stale configuration entries present in the backup routing-engine, the stale entries cannot be removed from master and backup routing-engine with 'commit synchronize' and 'commit synchronize force'.

In the dual Routing Engine scenario, the backup Routing Engine does not sync up the configuration change while deleting an inactivated interface/routing-instances from the master. So after the operation, the inactivated interface/routing-instances still exists on the backup Routing Engine.

This issue has been addressed via PR/1586229.

Workaround:

Step 1:

Check the stale entries in the backup RE via executing following command:

In config mode

Show | compare re1:/config/juniper.conf

Step 2:

Disable commit sync on the active RE > RE0.

deactivate system commit synchronize

commit

> Then login to RE1 and remove the stale entries which we saw in the first step

> commit

Step 3:

Login back to RE0 and enable commit sync

activate system commit synchronize

commit
