IP routing basics NOTE: The types of interfaces that appear in any figures other than the network diagrams for configuration examples are for illustration only. Some of them might be unavailable on your switch. IP routing overview Upon receiving a packet, a router determines the optimal route based on the destination address and forwards the packet to the next router in the path. -

Page 16: Ipv6 Static Routing Configuration
IPv6 static routing configuration Introduction to IPv6 static routing Static routes are manually configured. They work well in simple networks. Proper configuration and use can improve network performance and ensure enough bandwidth for important applications. However, static routes also have limitations. Any topology changes require manual configuration and modification to the relevant static routes. -
