Configuring High System Availability
This section describes high system availability (HSA), a feature that enables a router to continue
processing and forwarding packets after a planned or unplanned outage.
It includes the following topics:
•
•
•
•
•
HSA is the system default when two RSP2s, or an RSP2 and an RSP4/4+ (one designated as the "active"
or "master" and the other as the "standby" or "slave") are installed in a router and the active RSP2 fails.
The standby RSP2 takes over in this situation, known as a "cold standby." The router restarts without
manual intervention (for example, without inserting a new RSP) by rebooting with the standby RSP. The
standby has its own image and configuration file and acts as a single processor.
Caution To ensure proper functioning of the standby RSP2 in the event of an active RSP2 failure, the standby
RSP2 should have the same boot image, the same ROM monitor, and the same DRAM configuration
as the active RSP2.
