Deployment Guide
Congure both ends of the VLT interconnect trunk with identical PVST+ congurations. When you enable VLT, the show spanning-
tree pvst brief command output displays VLT information (refer to Verifying a VLT Conguration).

mVLT Conguration Example
The following example demonstrates the steps to congure multi-domain VLT (mVLT) in a network.
In this example there are two domains being congured. Domain 1 consists of Peer 1 and Peer 2; Domain 2 consists of Peer 3 and Peer 4 as
shown.
