Figure 146. VLT on Core Switches
Multiple VLT
A multiple VLT (mVLT) conguration allows two dierent VLT domains connected by a standard LACP LAG to form a loop-free Layer
2 topology in the aggregation layer.
This conguration supports a maximum of four (4) units, increasing the number of available ports and allowing for dual redundancy of
the VLT. The following illustration shows how the core/aggregation port density in the Layer 2 topology is increased using mVLT. For
inter-VLAN routing and other Layer 3 routing, a separate Layer 3 router is required.
