RP redundancy during RP reload

Updated: July 1, 2026

Want to summarize with AI?

Describes how the active and standby route processors respond when an operator runs the reload command on an active RP.

The reload command causes the active RP to reload the Cisco IOS XR software. When an RP reload occurs, the RPs respond in these ways:

If a standby RP is installed and ready for switchover, the standby RP becomes the active RP. The original active RP reboots and becomes the standby RP.
If the standby RP is not in the ready state, then both RPs reboot. The first RP to boot successfully adopts the role of active RP.
