Secure Domain Routers
Cisco CRS-1 routers and Cisco XR 12000 Series Routers can be partitioned into multiple, independent
routers known as secure domain routers (SDRs). Every router ships with a default SDR, which is called
the owner SDR because it by default owns all RPs and line cards installed in the routing system. To build
additional SDRs, you must create each SDR using configuration commands, name the SDR, assign RP,
DRP, and line cards to the SDR, and then configure the interfaces on the line cards on the new SDR. An
SDR is a group of cards within a router that is configured to operate as an independent router. SDRs that
are created with configuration commands are called named SDRs and are configured with custom names
to distinguish them from the owner SDR and other named SDRs.
