Routing protocol performance can be symptomatic of general router problems. Routing protocol problems can be seen if the router CPU is overburdened or memory is fully utilized.
Transient events, such as SNMP communication or a heavy traffic load, can temporarily spike the CPU. High CPU utilization is a concern when it becomes on-going. Signs of CPU oversubscription include dropped packets, increased latency, slow response to telnet and console, and when the router skips routing updates.
