mVLT Configuration Example

The following example demonstrates the steps to configure multi-domain VLT (mVLT) in a network.

In this example there are two domains being configured. Domain 1 consists of Peer 1 and Peer 2; Domain 2 consists of Peer 3 and Peer 4 as shown.
Figure 1. mVLT Configuration ExampleIllustration of an mVLT configuration.

In Domain 1, configure Peer 1 first, 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.

In Domain 1, configure 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 TenGigabitEthernet 0/8-9
                                 Domain_1_Peer1#no shutdown
                                 
                                 Domain_1_Peer1(conf)#vlt domain 1000
                                 Domain_1_Peer1(conf-vlt-domain)#peer-link port-channel 1
                                 Domain_1_Peer1(conf-vlt-domain)#back-up destination 10.16.130.11
                                 Domain_1_Peer1(conf-vlt-domain)#system-mac mac-address 00:0a:00:0a:00:0a
                                 Domain_1_Peer1(conf-vlt-domain)#unit-id 0
                              

Configure mVLT on Peer 1

Domain_1_Peer1(conf)#interface port-channel 100
                                 Domain_1_Peer1(conf-if-po-100)#switchport
                                 Domain_1_Peer1(conf-if-po-100)#vlt-peer-lag port-channel 100
                                 Domain_1_Peer1(conf-if-po-100)#no shutdown
                              

Add links to the mVLT port-channel on Peer 1

Domain_1_Peer1(conf)#interface range tengigabitethernet 0/16 - 17
                                 Domain_1_Peer1(conf-if-range-te-0/16-17)#port-channel-protocol LACP
                                 Domain_1_Peer1(conf-if-range-te-0/16-17)#port-channel 100 mode active
                                 Domain_1_Peer1(conf-if-range-te-0/16-17)#no shutdown
                              

Next, configure the VLT domain and VLTi on Peer 2

Domain_1_Peer2#configure
                                 Domain_1_Peer2(conf)#interface port-channel 1

                                 Domain_1_Peer2#no shutdown
                                 
                                 Domain_1_Peer2(conf)#vlt domain 200
                                 Domain_1_Peer2(conf-vlt-domain)#peer-link port-channel 1
                                 Domain_1_Peer2(conf-vlt-domain)#back-up destination 10.16.130.12
                                 Domain_1_Peer2(conf-vlt-domain)#system-mac mac-address 00:0a:00:0a:00:0a
                                 Domain_1_Peer2(conf-vlt-domain)#unit-id 1
