Warning: The following warnings were generated during the 'netlab initial' processing
Warning: cli: Lab topology source file /home/pipi/net101/tools/tests/integration/ospf/ospfv2/06-vlan-mtu.yml has been modified


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.
