1.
MTU REG_DWORD Number in octets
Default: 0 (That is, use the value supplied by the adapter.)

Specifies the maximum transmission unit size of an interface. Each interface

used by TCP/IP may have a different MTU value specified. The MTU is
usually determined through negotiation with the lower driver, using that

lower driver value. However, that value may be overridden.

Ideally, the MTU should be large enough to hold any datagram in one frame.
The limiting factor is usually the technology making the transfer. Some
technologies limit the maximum size to as little as 128; Ethernet limits

transfers to 1500; and proNet-10 allows as many as 2044 octets per frame.

Datagrams larger than the MTU value are automatically divided into smaller
pieces called fragments; size is a multiple of eight octets. Fragmentatio
n
usually occurs somewhere through which the traffic must pass whose MTU
is smaller than the encapsulated datagram. If fragmentation occurs, the

fragments travel separately to the destination computer, where they are

automatically reassembled before the datagram is processed.

2.
RouterMTU REG_DWORD Number in octets
Default: 0 (That is, use the value supplied by the lower interface.)
Specifies the maximum transmission unit size that should be used when the
destination IP address is on a different subnet. Each interface used by

TCP/IP may have a different RouterMTU value specified. In many
implementations, the value of RouterMTU is set to 576 octets. This is the
minimum size that must be supported by any IP node. Because modern
routers can usually handle MTUs larger than 576 octets, the default value for

this parameter is the same value as that used by MTU.
