High Availability Overview
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.
