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: - Consolidated package mode - Subpackage mode 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 Router) do not support ISSU upgrade or downgrade. Instead subpackage software upgrade is supported only if the router is running in subpackage mode.Traffic loss cannot be avoided during the installation of the ESP package as a part of ISSU.
