The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Beginning with Cisco NX-OS Relese 5.0(3), the Overlay Transport Virtualization (OTV) is available.
This chapter provides examples on configuring OTV.
This example displays how to configure a basic OTV network that uses the configuration default values:
!Configure the physical interface that OTV uses to reach the ! DCI transport infrastructure interface ethernet 2/1 ip address 192.0.2.1/24 ip igmp version 3 no shutdown !Configure the VLAN that will be extended on the overlay network ! and the site-vlan vlan 2,5-10 ! Configure OTV including the VLANs that will be extended. feature otv otv site-vlan 2 otv site-identifier 256 interface Overlay1 otv control-group 239.1.1.1 otv data-group 232.1.1.0/28 otv join-interface ethernet 2/1 !Extend the configured VLAN otv extend-vlan 5-10 no shutdown
The following example displays how to configure load balancing on two edge devices in the same site:
Edge Device 1 interface ethernet 2/1 ip address 192.0.2.1/24 ip igmp version 3 no shutdown vlan 5-10 feature otv otv site-identifier 256 interface overlay 1 otv control-group 239.1.1.1 otv data-group 239.1.1.0/29 otv join-interface ethernet 2/1 otv extend-vlan 5-10 no shutdown Edge Device 2 interface ethernet 1/1 ip address 192.0.2.16/24 ip igmp version 3 no shutdown vlan 5-10 feature otv otv site-identifier 256 interface overlay 2 otv control group 239.1.1.1 otv data-group 239.1.1.0/29 otv join-interface ethernet 1/1 otv extend-vlan 5-10 no shutdown
