Hi Ruijing,
It seems that GTPU did not failed on the fib check.
Please add below items on your configuration:
sudo vppctl create gtpu tunnel src 192.168.1.22 dst 192.168.1.21 teid 13
encap-vrf-id 0 decap-next ip4
Thanks,
Hongjun

Hi Ruijing,
It seems that there may be some issue on the gtpu decapsulation.
Could you help to capture the traffic between the vpp1 side and vpp2 side?
Thanks,
Hongjun

Hi,
I tried vpp (18.04-release, 19.08.1-release) with gtpu. it cannot work. Could
you pls help?
Vpp1 setup:
sudo vppctl create host-interface name eth1
sudo vppctl set inter stat host-eth1 up
sudo vppctl set int mac address host-eth1 52:54:00:43:88:63
sudo vppctl set int ip add host-eth1 192.168.1.21/24
sudo vppctl show ip arp
sudo vppctl create gtpu tunnel src 192.168.1.21 dst 192.168.1.22 teid 13
sudo vppctl set int ip address gtpu_tunnel0 10.10.1.1/24
sudo vppctl set int stat gtpu_tunnel0 up
Vpp2 setup:
sudo vppctl create host-interface name eth1
sudo vppctl set inter stat host-eth1 up
sudo vppctl set int ip add host-eth1 192.168.1.22/24
sudo vppctl set int mac address host-eth1 52:54:00:12:ab:01
sudo vppctl create gtpu tunnel src 192.168.1.22 dst 192.168.1.21 teid 13
sudo vppctl set int ip address gtpu_tunnel0 10.10.1.2/24
sudo vppctl set int stat gtpu_tunnel0 up
vpp1:

vagrant@vpp1:/vagrant$ sudo vppctl ping 10.10.1.2
