CSS Permanent Flow & CSS Failover

I am trying to confirm (without access to a test lab at this stage) if established permanent flows are torn-down upon CSS box-to-box failover (Master/Standby) or if they are maintained and re-activated upon return failover.

Looking at established flows on both the Master and Backup CSS now, i can see flows on the Backup despite all Circuits being in a down-ipDisabled state.

If you have connection replication configured (ASR), then the permanent flows are replicated to the standby and will exist until the connection is closed by the client or the server.

If this is UDP, the connection will stay there forever.
