Summary
Leaf-Spine Fabric for SDN. Use SD-Fabric for example.
Details
- SD-Fabric has three main features
- Supports VLANs
- Supports IPv4 and IPv6 for both unicast and multicast addresses
- High availability in the face of link or switch failures
- Link aggregation and ECMP
- Link aggregation: combine multiple physical links into a single logical
link (more than one egress port; port groups)
- ECMP: Equal-cost multi-path routing; multiple paths to the same
destination with the same cost
- Scalability: up to 120k routes and 250k flows
- Do not go into the technical details of the implementation of SD-Fabrics
