Configuring Secure Domain Routers on Cisco IOS XR Software

Information About Configuring Secure Domain Routers

•DRPs are supported in the Cisco CRS-1 only. DRPs are not supported in the Cisco XR 12000 Series Routers.

Note DRPs can also be used to provide additional processing capacity in a Cisco CRS-1 router. 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. For information on using DRPs for additional processing capacity, see the Process Placement on Cisco IOS XR Software module in the Cisco IOS XR System Management Configuration Guide.

Using a RP Pair as the DSDRSC in a Cisco CRS-1 Router

In a Cisco CRS-1 router, RP pairs can also be used as the DSDRSC in non-owner SDRs.

•Single RPs cannot be used as the DSDRSC.

•Redundant RPs in a CRS-1 Series router are installed in slots RP0 and RP1 of each line card chassis.

•To assign an RP pair as the DSDRSC, complete the instructions in the “How to Configure Secure Domain Routers” section on page SMC-140.

Note Although an RP pair can be used as the DSDRSC in non-owner SDRs, we recommend the use of a redundant DRP pair to ensure DRP migration capability. See the “DSC Migration on Cisco CRS-1 Multishelf Systems” section on page SMC-136for more information.

DSC and DSDRSCs in a Cisco XR 12000 Series Router

In a Cisco XR 12000 Series Router, you can use a single RP or a redundant RP pair as the DSDRSC for each SDR. Redundant RP pairs must be installed in adjacent redundancy slots. The adjacent redundancy slots are as follows:

–Slot 0 and Slot 1

–Slot 2 and Slot 3

–Slot 4 and Slot 5

–Slot 6 and Slot 7

–Slot 8 and Slot 9

–Slot 10 and Slot 11

–Slot 12 and Slot 13

–Slot 14 and Slot 15

Review the additional information in this section for restrictions regarding RP usage in

Cisco XR 12000 Series Routers.

Note Only two RPs can be operational in any SDR on a Cisco XR 12000 Series Router.

Note DRPs are not supported in Cisco XR 12000 Series Routers.
