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.

Configuring Secure Domain Routers on Cisco IOS XR Software Information About Configuring Secure Domain Routers Removing a DSDRSC Configuration There are two ways to remove a DSDRSC from an SDR:  First remove all other nodes from the SDR configuration, and then remove the DSDRSC node. You cannot remove the DSDRSC node when other nodes are in the SDR configuration.  Remove the entire SDR. Removing an SDR name deletes the SDR and moves all nodes back to the owner SDR inventory. See the “Removi

This causes an inconsistent system view in the named SDR using DRP paired across the rack in which the DRP loses control Ethernet connectivity, but the LR plane is still working and can bring the named SDR into an inconsistent view if the named SDR is across the rack. To support DSC migration in Cisco IOS XR Software Release 3.3.2 and higher, we recommend that you:

This operation takes some time, during which routing protocols such as BGP that use loopback or null interfaces are affected. Similarly, tunnels and bundles must also be recreated, affecting protocols such as MPLS. As a result, there is a drop in traffic in the default or owner SDR. Note In Cisco IOS XR Software Release 3.3.0 and higher, DSC migration is
