    The alarm is for "host 1", indicating the routing-engine in slot 1.  Your current master RE is probably slot 0.  You could either bring the link-up, on the backup RE, or ignore the links status of fxp0 on RE1.

     

    The command to do that is 'set chassis alarm management-ethernet link-down ignore'.  If you only want to do this on RE1, you will need to apply this, using routing-engine specific group inheritance.

     

    Here is an example, showing how to create configuration groups for each routing-engine, and apply them.
