Configuring IP Unicast Routing
This chapter describes how to configure IP unicast routing on the Catalyst 3750 Metro switch.
Note For more detailed IP unicast configuration information, refer to the Cisco IOS IP and IP Routing
Configuration Guide for Release 12.1. For complete syntax and usage information for the commands
used in this chapter, refer to the Cisco IOS IP and IP Routing Command Reference for Release 12.1.
This chapter consists of these sections:
• Understanding IP Routing, page 28-2
• Steps for Configuring Routing, page 28-3
• Configuring IP Addressing, page 28-4
• Enabling IP Unicast Routing, page 28-17
• Configuring RIP, page 28-18
• Configuring IGRP, page 28-23
• Configuring OSPF, page 28-28
• Configuring EIGRP, page 28-37
• Configuring BGP, page 28-43
• Configuring ISO CLNS Routing, page 28-63
• Configuring Multi-VRF CE, page 28-76
• Configuring Protocol-Independent Features, page 28-86
• Monitoring and Maintaining the IP Network, page 28-100
Note When configuring routing parameters on the switch and to allocate system resources to maximize the
number of unicast routes allowed, you can use the sdm prefer routing global configuration command
to set the Switch Database Management (SDM) feature to the routing template. For more information on
the SDM templates, see Chapter 6, “Configuring SDM Templates,” or refer to the sdm prefer command
in the command reference for this release.
