Which of the following is the purpose of configuring IS-IS fragmentation on an IS-IS device?
Correct Answer: B
* IS-IS (Intermediate System to Intermediate System) protocol has a limit on the size of Link-State PDUs (LSPs). * Why Fragmentation? * LSPs contain routing and topology information. * If the LSP exceeds the maximum size, fragmentation allows the device to store and forward more routes by breaking them into smaller LSPs. * Key Point: IS-IS fragmentation is essential in large-scale networks where routing tables grow beyond the default LSP size limit. # Reference: Huawei HCIE-Datacom Guide - IS-IS Protocol and Route Scaling
