Maximum transfer unit (MTU) for this sham link.
This is the maximum packet size in bytes for packets sent
over the sham link. This size excludes link layer headers
but includes IP headers and higher-level headers.
Normally, DC-OSPF will limit sent PDUs (protocol data
units) to less than or equal to this size. However, if
DC-OSPF cannot construct a valid OSPF PDU smaller than or
equal to this size then it will send the smallest valid
PDU and assume that the IP stack will fragment the packet.
