Prerequisites for Working with Secure Domain Routers
Before configuring SDRs, the following conditions must be met:
- The router must be running the Cisco IOS XR software , including a designated shelf 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, see Cisco IOS XR Getting Started Guide for the Cisco CRS Router.
Required Cards for Each SDR
- Additional route processor (RP) pair, DRP or DRP pair must be installed in each line card (LC) chassis 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, see 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. The command reference guides include the task IDs required for each command. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator for assistance.
Software Version Requirements
- Cisco IOS XR Software Releases 2.0, 3.0, and 3.2 support only one owner SDR. 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 Cisco IOS XR Software Release 3.3.0 or higher.
Maximum SDR Configurations
- A maximum of eight SDRs are supported, including one owner SDR and up to seven non-owner SDRs.
