Cisco Systems 78-11741-02 manual Configuring IP Addressing, IP Addressing Task List

Configuring IP Addressing

This chapter describes how to configure IP addressing. For a complete description of the IP addressing commands in this chapter, refer to the “IP Addressing Commands” chapter of the Cisco IOS IP Command Reference, Volume 1 of 3: Addressing and Services publication. To locate documentation of other commands that appear in this chapter, use the command reference master index, or search online.

IP Addressing Task List

A basic and required task for configuring IP is to assign IP addresses to network interfaces. Doing so enables the interfaces and allows communication with hosts on those interfaces using IP. Associated with this task are decisions about subnetting and masking the IP addresses.

To configure various IP addressing features, perform the tasks described in the following sections. The task in the first section is required; the tasks in remaining sections are optional.

•Assigning IP Addresses to Network Interfaces (Required)

•Configuring Address Resolution Methods (Optional)

•Enabling IP Routing (Optional)

•Enabling IP Bridging (Optional)

•Enabling Integrated Routing and Bridging (Optional)

•Configuring a Routing Process (Optional)

•Configuring Broadcast Packet Handling (Optional)

•Configuring Network Address Translation (Optional)

•Monitoring and Maintaining IP Addressing (Optional)

At the end of this chapter, the examples in the “IP Addressing Examples” section illustrate how you might establish IP addressing in your network.

Assigning IP Addresses to Network Interfaces

An IP address identifies a location to which IP datagrams can be sent. Some IP addresses are reserved for special uses and cannot be used for host, subnet, or network addresses. Table 3 lists ranges of IP addresses, and shows which addresses are reserved and which are available for use.
