Virtual Link Trunking (VLT)
VLT allows physical links between two chassis to appear as a single virtual link to the network core. VLT
eliminates the requirement for Spanning Tree protocols by allowing link aggregation group (LAG)
terminations on two separate distribution or core switches, and by supporting a loop-free topology. VLT
provides Layer 2 multipathing, creating redundancy through increased bandwidth and enabling multiple
parallel paths between nodes and load-balancing traffic where alternative paths exist.
