You’re binding and connecting to different IPs:
bind: vpp_echo socket-name /var/run/vpp.sock server uri tcp://172.16.1.1/1234
use-svm-api chroot prefix vpp1
connect: test echo client uri tcp://122.16.1.1/24 <tcp://122.16.1.1/24>
Moreover, you’re also mixing external echo app (bind) with the builtin one
(connect). Stick to using just one.
