Cisco Modern Networking Spine Leaf Lab with Cisco Packet Tracer

In this Lab for Spine Leaf use 5 Cisco Routers 2911 to simulate a modern Network Topology that is very resilient and just works.

Since today Cisco Packet tracer only support EBGP that is what is was used to route traffic between the Fabric (Spine/Leaf) however any router protocol could be used.

Here is the settings used for the Lab:

Putting together VXLAN with mobility will be awesome. but that will require other Network Virtualization software and other video =)

Thank you for watching.
