Network layer routing protocols provide the communication protocols and algorithms for determining routes to every destination and also for distributing the routing information throughout the network.

Many network security audits uncover weak security practices in regards to layer 3 protocols used to build corporate routing tables.

DDoS attacks can be amplified through SOHO routers that still use the Routing Information Protocol version 1, researchers warn.

Routing protocols designed for low power and lossy networks (LLNs) have become pivotal in realising the vast potential of the Internet of Things (IoT) and wireless sensor systems.
