RP Redundancy and Failover
Two RPs can be installed in slots RP0 and RP1 of a line card chassis to form a redundant set (see
Figure 7-10). RP redundancy is enabled by default in the Cisco IOS XR software.

Determining the Primary RP
During system startup, the first RP to boot with a valid Cisco IOS XR software boot package becomes
the active “primary RP.” The primary RP can in either slot RP0 or slot RP1. You can tell which RP is the
primary RP in the following ways:
• The primary RP can be identified by the green Primary LED on the faceplate of the card. The
primary RP is indicated when the Primary LED is on.
• The slot of the primary RP is indicated in the CLI prompt. For example:
RP/0/RP1/CPU0:router#
In this example, the prompt indicates that you are communicating with the primary RP in slot RP1.
See “CLI Prompt” section on page 2-4 for a complete description of the CLI prompt.
• Enter the show redundancy command in EXEC mode to display a summary of the primary and
standby RP status.
