Hi,
from Doc page
"You cannot configure a routing MTU size that exceeds the system MTU size.
If you change the system MTU size to a value smaller than the currently
configured routing MTU size, the configuration change is accepted, but not
applied until the next switch reset. When the configuration change takes
effect, the routing MTU size automatically defaults to the new system MTU
size."
It means that in dot1q tunnel and ospf scenario we can not take advantage of
system mtu routing because we are increase mtu.
Regards
