routing protocols : Classless routing protocols

The video tutorial explains how subnet masks are advertised in routing protocols, allowing routers to understand the exact network mask without assumptions. It covers the concept of variable length subnet masks (VLSM), which allows different interfaces to have different masks. The tutorial also discusses classless routing protocols, which support manual route summarization, and provides examples such as OSPF, EIGRP, and ISIS.
