It is working fine for vxlan and vxlan-gpe tunnels but IPSec it is not. We set physical interface MTU to be 1500 and IPSEC interface MTU to 1350 to give room for encryption. The issue we are seeing is packets are getting fragmented sent out after encryption and causing traffic is getting dropped. Is there any different way to enable fragmentation and then encryption each fragment on 18.10. Thanks in advance. Sam
