Hi guys,

Whether vpp support ip fragment reassembly on host-interface?
Can I use only" set interface mtu 2000 host-eth2 "to set mtu.

Here's my test result:
vpp+dpdk:
mtu 1500  when the packet size 1500+  it  dropped;
mtu 2000  when the packet size 2000+  it  dropped;
mtu 300  when the packet size < 1500 it passed;
no fragmentation in my test;
vpp without dpdk:
Configuring MTU is not effective.

Thanks,
xyxue
