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