Re: should we enable CEF on Tunnel inetrfaces

Hi, Cisco document reccommended that you can use CEF on your tunnel interfaces, you can verify CEF with this command "router#show cef interface fastEthernet 0/0/0'

this improved switching performance because only the destination mac-address is read and the packet is forwarded. have a look at the documents below for details. HTH
