Page 8: Ip Routing Basics
IP routing basics Overview IP routing directs the forwarding of IP packets on routers based on a routing table. This book focuses on unicast routing protocols. For more information about multicast routing protocols, see IP Multicast Configuration Guide. The term "router" in this chapter refers to both routers and Layer 3 switches. The types of interfaces that appear in any figures other than the network diagrams for configuration examples are for illustration only. -

Page 11: Configuring Static Routing
Configuring static routing Introduction Static route Static routes are manually configured. If a network's topology is simple, you only need to configure static routes for the network to work properly. The proper configuration and usage of static routes can improve network performance and ensure bandwidth for important network applications. -
Page 12: Configuring A Static Route
Configuring a static route Before you configure a static route, complete the following tasks: Configure the physical parameters for related interfaces. • Configure the link-layer attributes for related interfaces. • Configure the IP addresses for related interfaces. • Follow these guidelines when you configure a static route: The next hop address cannot be the IP address of a local interface (such as VLAN interface). -

Page 16: Configuring Ipv6 Static Routing
Configuring IPv6 static routing Overview 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. Static routes cannot adapt to network topology changes. If a fault or a topological change occurs in the network, the network administrator has to modify the static routes manually. -

NOTE: If you specify a broadcast interface, such as a VLAN interface, as the output interface for a static route, you must specify the next hop address. -
