[Edited Message Follows]
I tried to send the reverse traffic from 192.168.200.20 <-> 192.168.100.20.
I investigated further. It looks like DPDK is not transmitting the traffic on
the VPP n after it got decrypted from IPSEC.
Same issue but this time interface eth3 owned by DPDK on VPP1 is still up.
The local ping from VPP1 to host 192.168.100.20 looks good.
