MLAG can be used at various places in the network to eliminate bottlenecks and provide resiliency, including the spine layer and leaf layer. But the most common use case for M-LAG is using this feature at the Leaf layer. At the leaf of the network, servers with multiple interfaces connect to the switches using NIC …
In the new generation data center networking design, we have “clos” topologies which is based on network–based spine-and-leaf architecture. CLOS topology basically have 2 tier, Spine (Core) and Leaf (Access). Every leaf switch is connected to all Spine switches. The spine layer is the backbone of the network and is responsible for interconnecting all leaf …
With the rapid evolution of SDN, industry have started to separate networks as Underlay and Overlay. An overlay is a virtual network that is built on top of an underlying network infrastructure, underlay. It is the underlying network responsibility to deliver packets across networks. Here are summary of Underlay and its characteristics; – Physical infrastructure which …
