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.
