Example:

RP/0/RP0/CPU0:router(admin-config-sdr:rname

2)# pair drp1 primary

RP/0/RP0/CPU0:router(admin-config-sdr:rname

2)# location 0/0/* primary

RP/0/RP0/CPU0:router(admin-config-sdr:rname

2)# location 0/RP*/* primary

Specifies a DSDRSC for the non-owner SDR. You can assign a

redundant DRP pair, an RP pair, or a single DRP as the

DSDRSC. You cannot assign a single RP as the DSDRSC.

Every SDR must contain a DSDRSC.

•We recommend the use of DRPpairs as the DSDRSC for

all non-owner SDRs to ensure DSC migration in a

Cisco CRS-1 system. See the “DSC Migration on Cisco

CRS-1 Multishelf Systems” section on page SMC-136 for

more information.

•The primary keyword configures the RPs, DRPpair, or

DRP as the DSDRSC. If the primary keyword is not used,

the node is assigned to the SDR, but it is not be the

DSDRSC.

•If an RP is already assigned to the SDR, it must be removed

before a DRP or DRP pair can be assigned as the DSDRSC.

See the “Removing Nodes from a Secure Domain Router in

a Cisco CRS-1 Router” section on pageSMC-152.

To assign a DRP pair as the DSDRSC

To assign a DRP pair as the DSDRSC, you must first create a

DRP pair, as described in step 3 and step 4. After the DRP pair

is created, you can add the pair to the configuration with the

command pair pair-name. To assign the pair as the DSDRSC,

use the primary keyword.

To assign a single DRP node as the DSDRSC

The value of the partially-qualified-nodeid argument is entered

in the rack/slot/* notation. The node ID is specified at the slot

level, so the wildcard (*) is used to specify the CPU.

To assign an RP pair as the DSDRSC

The value of the partially-qualified-nodeid argument for RPs is

entered in the rack/RP*/* notation. This command assigns the

redundant RP pair as the DSDRSC. One RP is automatically

elected as the DSDRSC, and the second RP acts as the standby

DSDRSC.
