juniper mx – Can’t show invoke command to backup RE from master RE
I have an MX960 box that faced an issue as below.
Mater RE (RE1) can’t show any command invoke-on backup RE (RE0), for example: show version invoke-on all-routing-engines.
{master}
nms@MX960> request routing-engine login other-routing-engine

I checked logs on backup RE (RE0) and got that interface ESW port 13 (interface connects SCB0 and RE0) flapped several times. But then, it is up again, but from RE1, I still couldn’t show any command invoke-on backup RE (RE0).

From master RE, show chassis routing-engine, I see all REs (RE0 is backup an RE1 is master).
But from backup RE, show chassis routing-engine, state of master RE is Present.
**From RE0 (backup RE)**
