BPDU Guard and Root Guard are enhancements to Spanning Tree Protocol (STP) enhancements that improve the reliability of the protocol to unexpected events ad are primarily to ensure design enforcement ( integrity / security). There they must configured in specific locations in the networks.
In this post, I’m looking at network designs with ECMP cores using TRILL or SPB, I’m realising that STP is equally improved in terms of risk and performance by reducing the STP domain size which leads to better stability, reduced risk and impact mitigation
