Cisco VTS 2.4.1 Day Zero Configuration Examples
The following sections provide details about the different VTS deployment scenarios and the respective Day Zero configuration.
Note: For details about platforms that are supported in each role, see the Supported Platforms section in Cisco VTS Installation Guide.
● VTS Day Zero Configuration for Various Roles and Platforms
● Day Zero Configuration Changes Required on IOS XRv
● Underlay Day Zero Routing to Advertise for VTF and IOSXRv n/w to all Devices in Data Center Topology
● VTF - Day Zero Configuration on Non-VTEP Devices
● IOS XRv Day Zero Configuration for High Availability
VTS Day Zero Configuration for Various Roles and Platforms
The following sections provide examples of day zero configurations required on different platforms, based on their role.
Note: You need to replace the variables (IP addresses, passwords, and so on) in the examples below with values from your own system.
● Day Zero Configuration—IOS XRv
● Day Zero Configuration—Cisco Nexus 9300 or Cisco Nexus 9500 as ToR
● Day Zero Configuration—Cisco Nexus 7000/7700 as ToR
● Day Zero Configuration—Cisco Nexus 5600 as ToR
● Day Zero Configuration—Cisco Nexus 9300 or Cisco Nexus 9500 as DC Gateway
● Day Zero Configuration—Cisco Nexus 7000/7700 as DC Gateway
● Day Zero Configuration—Cisco Nexus 5600 as DC Gateway
● Day Zero Configuration—Cisco Nexus 9300 or Cisco Nexus 9500 or Cisco Nexus 5600 or Cisco Nexus 7000 as Spine
● Day Zero Configuration—Cisco ASR 9000 as DCI—VRF Peering Mode
● Day Zero Configuration—Cisco Nexus 7000 as DCI—VRF Peering Mode
● Day Zero Configuration—Cisco ASR 9000 as Integrated DCI (DCI and DC Gateway)
● Day Zero Configuration—Cisco Nexus 7000 as Integrated DCI (DCI and DC Gateway)
Important Notes
● In a datacenter, on the DCI the fabric facing loopback should be unique. This is because we construct the route distinguisher with fabric facing loopback and L3VNI (fabric-facing-loopback:L3VNI).

Underlay Day Zero Routing to Advertise for VTF and IOSXRv n/w to all Devices in Data Center Topology
The VTF IP address needs to be routed via the underlay network so that the VTF endpoint is advertised to all
the physical Leaf and Spine in the Data Center network.

BGP helps scale routes through the data center. For an extensive large data center, BGP provides better scalable control plane to route tenant VM based traffic. BGP protocol can also be used to scale and route VTF underlay network.

Ethernet Segment Identifier (ESI) Day Zero Configuration on TORs
Note: You have to disable VPC (no feature vpc) before enabling ESI feature. Different ESI groups/domains must have different ES-id or system MAC. In other words, duplicate ES-id and system MAC are not allowed among ESI groups. This needs to be guaranteed by providing the correct Day Zero configurations for ESI on Cisco Nexus 9000 switches.
