Loopback IP Health check in DSR structure

Hi all,

 

We health check our Loopback IP in DSR architecture.

 

The Alias address in Monitor is Loopback IP.

 

Of course, health check is normal.

 

Here! Added new member to existing pool.

 

Even though the new member did not set up the Loopback IP, the health check is normal.

 

Is this normal? Does the existing Member's Loopback IP have an effect?

 

Thanks.
