Is it possible to define MTU on an interface with different values for IPv4 and IPv6 on a Linux machine?
It seems that command ifconfig MTU defines the same MTU for both IPv4 and IPv6.
Any help is appreciated.

This might help you. Setting a higher value in
/proc/sys/net/ipv6/conf/eth0/mtu
command sudo sh -c "echo 0 > /proc/sys/net/ipv6/conf/eth0/mtu
But turns out it can be reset regularly by the router. Quote from a comment in this link. How to configure a large mtu (linux)
This value gets updated/reset regularly through Router Advertisement. RA can be disabled by writing 0 to accept_ra in the same folder under /proc.
