Example: Consider the following physical topology:
and logical topology is A <-> B. Activation can be done in two ways: A – S1 – S2 – B and A – S1 – S3 – S2 – B. iLO deliberately chooses the first one, since it is shorter.
The same is true for L2 switches. If S1, S2 and S3 switches in the diagram above are L2 switches, iLO will create VLAN on S1 and S2 switches, leaving S3 switch intact.
