eVLT Conguration Example
The following example demonstrates the steps to congure enhanced VLT (eVLT) in a network.
In this example, you are conguring 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, congure Peer 1 st, then congure 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, congure the VLT domain and VLTi on Peer 1.

Congure eVLT on Peer 1.

Add links to the eVLT port-channel on Peer 1.
