[DARYLE DIANIS]

I might have a need to use CEF in my WAN. Is it a good, dependable technology compared to IMUXing and IMA? Any succes stories or horror stories with CEF?

thanks,

Daryle

Hello,

CEF would definitely be your choice, since it is much less processor intensive than process-switching.

Not sure if you have a CCO login, but if you do, check the following document about the benefits and restrictions of CEF (this document is bsed on IOS version 12.2):
