Redundancy information for node 0/RP1/CPU0:
==========================================
Node 0/RP1/CPU0 is in ACTIVE role
Partner node (0/RP0/CPU0) is in STANDBY role
Standby node in 0/RP0/CPU0 is ready
Standby node in 0/RP0/CPU0 is not NSR-ready <<<<<<<<<
-- snip --
Current active rmf state for NSR: Not ready
Reason for standby not NSR-ready
1062 0/RP1/CPU0 te_control Standby not connected <<<<<<<<<<<<
-- snip --
------
Conditions
On the device that sr-te (or mpls-te) and performance-measurement are configured on, remove performance-measurement.
after that, when RP switchover happens, NSR state will not able to move ready.
Workaround
Configure performance-measurement to get the NSR to ready state.
