Software Upgrade Process
Cisco ASR 1000 Series Routers support the following software upgrade procedures:
In Service Software Upgrades (ISSU) for redundant platforms—The ISSU process allows software
•
to be updated or otherwise modified while packet forwarding continues with minimal interruption.
ISSU supports two different software upgrade modes:
–
–
The supported platforms include Cisco ASR 1006 and Cisco ASR 1013 Routers.
Upgrade process with service impact for nonredundant platforms—Non-hardware-redundant
•
chassis models (such as the Cisco ASR 1001 Router, Cisco ASR 1002 Router and Cisco ASR 1004
