Hi Benoit,

We tried
vpp# ping ?
  ping              ping {<ip-addr> | ipv4 <ip4-addr> | ipv6 <ip6-addr>}
[ipv4 <ip4-addr> | ipv6 <ip6-addr>] [source <interface>] [size
<pktsize:60>] [interval <sec:1>] [repeat <cnt:5>] [table-id <id:0>] [burst
<count:1>] [verbose]
vpp# ping 50.50.50.1 source gtpu_tunnel0 repeat 1
Failed: no source address for egress interface

Statistics: 0 sent, 0 received, 0% packet loss
vpp#

It is not working

Thanks,
Regards,
Venu
