Hello,
I wrote ping for creating the traffic on the externally facing interfaces, so I
didn't do anything special to make the loopback work.
Why do you need to ping the loopback ?

Hello,
In a vppctl, ping to loop0 does not reply. Is it correct behavior?

Hello,
1) After setting IP address of interface, it is just conventional check.
2) After creating bridge-domain, set loop interface as BVI(Bridge Virtual
Interface). Then ping to BVI
