Hi Matt,

I would tend to agree with you. The interface’s IP addresses should not be 
programmed in the FIB if the interface is down.

Objet : [vpp-dev] loopback admin status

Hi,

If I create a loopback interface and configure an IP address on it, I am able 
to ping that IP address from another host regardless of whether the admin 
status of the loopback is up or down. Is that intentional? I'm trying to figure 
out if this is something that can be "fixed" or if the current behavior is the 
way it's supposed to be.

If I use a loopback as an endpoint for services and want to take the services 
offline temporarily, it would be convenient to be able to take the interface 
down and have the services effectively be disabled.

-Matt
