Cisco Systems 1000 Series Manual De Usuario

Cisco High Availability (HA) enables network-wide protection by providing fast recovery from faults 
that may occur in any part of the network. With Cisco High Availability, network hardware and software 
work together and enable rapid recovery from disruptions to ensure fault transparency to users and 
network applications.

The unique hardware and software architecture of the Cisco ASR 1000 Series Routers is designed to 
maximize router uptime during any network event, and thereby provide maximum uptime and resilience 
within any network scenario.

This guide covers the aspects of High Availability that are unique to the Cisco ASR 1000 Series Routers. 
It is not intended as a comprehensive guide to High Availability, nor is it intended to provide information 
on High Availability features that are available on other Cisco routers that are configured and 
implemented identically on the Cisco ASR 1000 Series Routers. The Cisco IOS feature documents and 
guides should be used in conjunction with this chapter to gather information about High 
Availability-related features that are available on multiple Cisco platforms and work identically on the 
Cisco ASR 1000 Series Routers.

Your software release might not support all the features documented in this module. For the latest feature
