eVLT Configuration Example
The following example demonstrates the steps to configure enhanced VLT (eVLT) in a network.
In this example, you are configuring 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, configure Peer 1 fist, then configure 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.
