Monitoring Redundant Routing Engines

You monitor redundant Routing Engines to ensure that system processes function normally, such as routing protocols, packet forwarding tables, router interfaces, system management, JUNOS software and file system storage, and monitoring functions. (See Table 108.)

This chapter describes how to monitor redundant Routing Engines. For more information about monitoring Routing Engines, see Monitoring the Routing Engine. See also the applicable router hardware installation guide.
