It seems that VPP can't ping the ip of a host-interface, is this expected?

setup:
ip link add name vpp1out type veth peer name vpp1host
ip link set dev vpp1out up
ip link set dev vpp1host up
ip add add 10.10.1.1/24 dev vpp1host

vppctl  create host-interface name vpp1out
vppctl set int state host-vpp1out up
vppctl set int ip address host-vpp1out 10.10.1.2/24

Testing:
On host, ping both 10.10.1.1 and 10.10.1.2 work fine.
>From VPP1, ping 10.10.1.2 seem not working. Is this expected?
