Cisco router ip cef
Posted on 2011-09-28
I am migrating my config from an old Cisco router to a ASR 1001.
Part of the config I am migrating over it not coming over, and it is a process I have never heard about.
ip cef - it is asking for additional options that I am unfamiliar with
Therefore, when I go to configure my interface, it states :
in Interface GigabitEthernet 0/0/0
ip nbar protocol-discovery - because of the ip cef cmd issue
no ip mroute-cache - says to use mibs instead ? The above command is deprecated. Use MFIB commands instead.
What is this IP CEF (from a knowledge learning perspective)? And what is the correct attribute that I should add to the end of this cmd ?
