Check the Routing CPU Memory Usage
Purpose
Software processes on the router can consume a considerable amount of CPU and memory. The routing protocol process (rpd) can consume enormous amounts of memory to store information needed for the operation of routing and related protocols, such as Border Gateway Protocol (BGP), Open Shortest Path First (OSPF), Intermediate System-to-Intermediate System (ISIS), Resource Reservation Protocol (RSVP), Label Distribution Protocol (LDP), and Multiprotocol Label Switching (MPLS).
Steps To Take
To verify the traffic passing through the router and check memory utilization, follow these steps:
