We have a 7206 router used as our internet router and have BGP facing our ISP and EIGRP on the inside. The CPU is really high and I noticed that CEF is not enabled. Fastswitching is enabled though.
Somewhere along the line someone said that CEF should not be enabled because it conflicts with something in the router. (really vague eh?)
Anyway, is there a reason why CEF should ever be disabled?
