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.

What is the primary benefit of advertising subnet masks in routing protocol advertisements?

• It reduces the size of routing tables.

• It allows for automatic network configuration.

• Routers can see the exact network mask without assumptions.

• It increases the speed of data transmission.
