pls can anybody help. we have three routers here. The core router (7200)is responsible for connectivity to clients on our metro network. it has a DRAM of 96M and flash memory of 16M. Natting was done on this core router for internet connectivity for clients. A 2611 router was connected directly to a tier one provider . Caching was also done on the 3rd router which has an interface to the two other routers
The show processes cpu on the 7200 router reveals close to 100%. Each time the memory goes high, the whole network goes down. and the router has to be restarted at those period.
Can sommebody please suggest a way out of this problem.
