If you are running OSPF between 2 routers and the MTU is not the same
between them, then the routers will be stuck in exstart mode.
They will never become neighbors. Debug ip ospf adj will actually show you
that the MTU is the cause.

So watch out.

Hi Emad,

MTU specifies the maximum size of a packet. Packets under that size are
perfectly acceptable and will be forwarded normally.
