This default route is configured for testing purposes, as described in the next section. The access switch (A1) is used to generate ICMPtest PINGs to a loopback interface on CR1. This default route points to Dell#2’s VLAN 800 SVI interface. It’s in place to ensure that routedtest traffic has Dell#2’s MAC address as the destination address in the Ethernet frame’s headerWhen 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 thedefault gateway used, Dell-1 routes the packet to R1. Similarly, if the packet reaches Dell-2, irrespective of the default gateway used, Dell-2routes the packet to R1.eVLT Configuration ExampleThe 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, asshown 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.Figure 144. eVLT Configuration ExampleeVLT Configuration Step ExamplesIn Domain 1, configure the VLT domain and VLTi on Peer 1.Domain_1_Peer1#configureDomain_1_Peer1(conf)#interface port-channel 1Domain_1_Peer1(conf-if-po-1)# channel-member TenGigabitEthernet 1/8-1/9Domain_1_Peer1(conf)#vlt domain 1000Domain_1_Peer1(conf-vlt-domain)# peer-link port-channel 1Domain_1_Peer1(conf-vlt-domain)# back-up destination 10.16.130.11Domain_1_Peer1(conf-vlt-domain)# system-mac mac-address 00:0a:00:0a:00:0aDomain_1_Peer1(conf-vlt-domain)# peer-routingDomain_1_Peer1(conf-vlt-domain)# unit-id 0Configure eVLT on Peer 1.Domain_1_Peer1(conf)#interface port-channel 100Domain_1_Peer1(conf-if-po-100)# switchportVirtual Link Trunking (VLT) 1017
