This lab tests OSPF adjacencies on VLAN interfaces and trunks with non-default
MTU settings. The adjacency establishment could fail due to MTU mismatch.
Failure to establish X2-DUT adjacency means that the VLAN interface does not
get the correct MTU. Failure to establish X1-DUT adjacency indicates a
potential problem with system MTU. Failure to establish X3-DUT adjacency
indicates the MTU is not set correctly on VLAN/SVI interface.
