Exploring Routing Protocols and Network Scaling Challenges

This chapter delves into experiences with a large network using EIGRP, challenges related to scale and mesh complexity, and potential solutions like network segmentation. It discusses the benefits of multi-area OSPF environments, comparisons between OSPF and ISIS, the usage of BGP in data center topologies, and the evolving landscape of routing protocol knowledge. The conversation also covers newer protocols like Rift and OpenR, usage of message buses for flooding mechanisms, implementation considerations for OSPF V3, doubts about its effectiveness in certain networks, and the limited use cases of the Babel routing protocol.
