Setup Guide
This default route is congured for testing purposes, as described in the next section. The access switch (A1) is used to generate ICMP
test PINGs to a loopback interface on CR1. This default route points to DellEMC#2’s VLAN 800 SVI interface. It’s in place to ensure that
routed test trac has DellEMC#2’s MAC address as the destination address in the Ethernet frame’s header
When A1 sends a packet to R1, the VLT peers act as the default gateway for each other. If the packet reaches Dell-1, irrespective of the
default gateway used, Dell-1 routes the packet to R1. Similarly, if the packet reaches Dell-2, irrespective of the default gateway used, Dell-2
routes the packet to R1.
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.

eVLT Conguration Step Examples
In Domain 1, congure the VLT domain and VLTi on Peer 1.
Domain_1_Peer1#configure
Domain_1_Peer1(conf)#interface port-channel 1
Domain_1_Peer1(conf-if-po-1)# channel-member GigabitEthernet 1/8-1/9

Congure eVLT on Peer 1.
