Prerequisites for Configuring Secure Domain Routers
Before configuring SDRs, the following conditions must be met:
Initial configuration
The router must be running the CiscoIOS XR software, including a Designated System Controller
(DSC).
The root-system username and password must be assigned as part of the initial configuration.
For more information on booting a router and performing initial configuration, refer to
Cisco IOS XR Getting Started Guide.
Required cards for each SDR
In Cisco CRS-1 routers, an additional RP pair, DRP or DRP pair must be installed in each line card
(LC) chassis to manage each SDR in the system.
In Cisco XR 12000Series Routers, an additional RP or RP pair must be installed to manage each
SDR in the system.
For additional information on DRPs, refer to Cisco CRS-1 Carrier Routing System 16-Slot Line Card
Chassis System Description. For instructions on installing DRPs, refer to Installing the Cisco CRS-1
Carrier Routing System 16-Slot Line Card Chassis.
Task ID requirements
You must be in a user group associated with a task group that includes the proper task IDs for SDR
commands.
For detailed information about user groups and task IDs, see the Configuring AAA Services on
Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.
Software Version Requirements for the CiscoXR 12000 Series Router
Multiple SDRs, including non-owner SDRs, are supported on CiscoXR 12000 Series Router
running CiscoIOS XR Software Release 3.2 or higher.
Software Version Requirements for the CiscoCRS-1
Cisco IOS XR Software Releases 2.0, 3.0, and 3.2 support only one owner SDR on the CiscoCRS-1.
Multiple (non-owner) SDRs are not supported in these releases. The owner SDR cannot be added or
removed from the configuration.
Multiple SDRs, including non-owner SDRs, are supported on CiscoCRS-1 running
Cisco IOS XR Software Release 3.3.0 or higher.
Maximum SDR configurations
The Cisco CRS-1 supports a maximum of eight SDRs, including one owner SDR and up to seven
non-owner SDRs.
For the CiscoXR 12000 Series Router, we recommend a maximum of four SDRs, including one
owner SDR and up to three non-owner SDRs.
