Some of the content i had committed during the early days of the blog, specifically on VLT – continues to receive a lot of traffic/queries.
Continued from Part 1. VLANs/Gateways terminate on Switch. Single Edge VLAN between FW and BCF. Default/static route in each direction. For Comparison with traditional NOS,
Before talking about the components, some quick observations on the Cloud Fabric Deployment considerations. Often, BSN Cloud Fabric may be the first SDN venture for
Big Switch’s Big Cloud fabric decouples the logical topology from the physical. The constructs are familiar – the implementation nuances are easily assimilated, once adequate
A short & sharp comparison of Layer 3/ECMP Leaf & Spine vs. Layer 2 Multi-chassis Link Aggregation, e.g. Dell EMC VLT (Virtual Link Trunking) Topologies.
In essence, Spline collapses the Leaf & Spine functions – much like the Functions of Core & Aggregation Layers in a traditional 3-tier topology, would
Software Defined and Open Networking as a topic of interest, crops up in close to 80% of all Data Center opportunities I engage in. Even
Core Config Options: First Hop/Gateway Redundancy: VRRP: Same Switch hosts VRRP and STP Master-ship for deterministic forwarding @ L2/L3 and eliminate suboptimal forwarding path. In
. Cisco offers three solutions for eliminating STP. These comprise the stacking feature on 3750/2950 models, VSS on 6500s, and vPC on Nexus 5k/7k platforms.
