Cisco XR 12000 Series Router SIP and SPA Software Configuration Guide, Release 3.2
Release 3.2, OL-6396-01, Rev.A1 January 9, 2006
Chapter 5 Overview of Packet over SONET SPAs
Supported Features
Although the default HA mode is Stateful Switchover (SSO) on a Cisco XR 12000 Series Router,
the router automatically falls back to RPR mode for unsupported devices. Therefore, RPR is used
with the SIP on a Cisco XR 12000 Series Router, and no additional configuration is required to
implement HA with a SIP on a Cisco XR 12000 Series Router.
More information about HA on the Cisco 7304 router can be found at the following URL:
