eVLT Conguration Example
The following example demonstrates the steps to congure enhanced VLT (eVLT) in a network.
In this example, you are conguring two domains. Domain 1 consists of Peer 1 and Peer 2; Domain 2 consists of Peer 3 and Peer 4, as
shown in the following example.
In Domain 1, congure Peer 1 st, then congure Peer 2. When that is complete, perform the same steps for the peer nodes in Domain 2.
The interface used in this example is TenGigabitEthernet.

In Domain 1, congure the VLT domain and VLTi on Peer 1.
