xfrm:fragmented ipv4 tunnel packets in inner interface

2020-10-08 Thread Lina Wang
In esp's tunnel mode,if inner interface is ipv4,outer is ipv4,one big packet which travels through tunnel will be fragmented with outer interface's mtu,peer server will remove tunnelled esp header and assemble them in big packet.After forwarding such packet to next endpoint,it will be dropped
