Hi I have an Openstack OVS/VXLAN setup with MTU of 1400. I have 2 Vms running on 2 different compute nodes With ipv4 I am able to perform a ping with packet size of 1500 which is above the MTU and it works as fragmentation happens
Now with ipv6 I try the same test ubuntu@testclient1:~$ ping6 -c10 -s 1500 2001:45::f816:3eff:fea2:d1b5 PING 2001:45::f816:3eff:fea2:d1b5(2001:45::f816:3eff:fea2:d1b5) 1500 data bytes ^C And the ping fails. I wanted to do this since I had a UDP performance test with 8K packet size and noticed that packets were not going through So how does one deal with larger packets above MTU size on these ipv6 tenant networks Ajay
