We have two sites and each site uses IPSec vpn over the internet as WAN link.
If we set up VxLAN on each site, how can we settle the problem of transmitting of Jumbo frame required for VxLAN header through our internet WAN link?
Can the Edge router on each WAN side can perform fragmentation of frame to achieve the goal?
Thanks

You can set the interface mtu to a value to allow for VxLAN + IPSec etc. overhead.
HTH.

For the WAN side, it is supposed the routers over the internet are owned by isp or other providers, we cannot configured the mtu size for jumbo frame. So is there any workaround?

You should set the mtu on the server or the router closest to where VxLAN packets originate.

What about the routers/switches between the whole path of the network? Are those of them required to make any configuration changes (eg set mtu size)?
