In an EBGP setup with different AS numbers for spine and leaf devices, all BGP routes advertised by a leaf device will be accepted on the spine devices as they are considered external routes. Additionally, a leaf device will accept all BGP routes received from the spine that were originated from another leaf device, enabling full connectivity within the fabric.

EBGP Configuration for IP Fabric

In ZTP, the image storage service and the DHCP server can be running on different server hosts, allowing for flexibility in network design. When a switch is booted, DHCP requests are sent through both the management interface and attached revenue ports. This ensures that the switch can retrieve its configuration from the network regardless of how it's connected.

In a Clos data center network, scaling the available bandwidth to support more east-west traffic can be effectively achieved by either adding more leaf devices (A) or more spine devices (C). Adding leaf devices increases the total number of endpoints in the network, thereby providing additional paths and bandwidth for east-west traffic. Similarly, adding spine devices increases the interconnectivity within the network, offering more paths for traffic to flow through, which helps in handling higher volumes of east-west traffic. Both approaches work towards enhancing the overall capacity and efficiency of the network.

In a spine and leaf-based IP fabric, when a device or link fails, the traffic is rerouted within the fabric (A), ensuring high availability and resiliency. This architecture is designed to dynamically adapt to changes and reroute traffic as needed. Furthermore, Clos networks, which are the basis for spine-leaf architectures, demonstrate good scaling features (D) as they allow for easy expansion of the network by adding more spine or leaf switches without significant changes to the existing infrastructure.
