Configuring Secure Domain Routers on
Cisco IOS XR Software
Secure domain routers (SDRs) are a means of dividing a single physical system into multiple logically
separated routers. SDRs are isolated from each other in terms of their resources, performance, and
availability.
Note SDRs were previously known as Logical Routers (LRs). The name was changed for Release 3.3.0.
