This lab tests OSPFv3 adjacencies on VLAN interfaces 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.
