In this chapter, you learned about implementing path control. The chapter focused on the following topics: ■ Redundant network considerations including resiliency, availability, adaptability, per- formance, support for network and application services, predictability, and asymmet- ric traffic. ■ Path control tools including a good addressing design, redistribution and other routing protocol characteristics, passive interfaces, distribute lists, prefix lists, administrative distance, route maps, route tagging, offset lists, Cisco IOS IP SLAs, and PBR. (Advanced tools covered briefly include Cisco IOS OER, virtualization, and Cisco WAAS.) ■ Offset lists, a mechanism for increasing incoming and outgoing metrics to routes learned via EIGRP or RIP. Configuration of offset lists is performed with the offset- list {access-list-number | access-list-name} {in | out} offset [interface-type interface- number] router configuration command. Verification of offset lists can be per- formed with the traceroute command, the show ip route command, and the show ip eigrp topology command. ■ Cisco IOS IP SLAs, which use active traffic monitoring, generating traffic in a con- tinuous, reliable, and predictable manner, to measure network performance. IOS IP
