How to Configure Secure Domain Routers
To create an SDR, configure an SDR name and then add nodes to the configuration. In CiscoCRS-1
routers, at least one node in each SDR must be explicitly configured as the DSDRSC. In the
Cisco XR 12000 Series Router, the DSDRSC is created automatically when you add an RP to the
configuration.
After the SDR is created, you can add or remove additional nodes and create a username and password
for the SDR. See the following sections for instructions.

Creating SDRs in a Cisco CRS-1 Router

To create a non-owner SDR in a CiscoCRS-1 router, create an SDR name, add a DSDRSC, and then add
additional nodes to the configuration. After the SDR is created, you can create a username and password
for the SDR to allow additional configuration.
Note The Cisco CRS-1 supports a maximum of eight SDRs, including one owner SDR and up to seven
non-owner SDRs.
