During a CEF packet rewrite, which of the following changes are NOT made to the packet?

• 300-420 : All Parts

There is no Layer 2 TTL in the packet, so the Layer 2 time to live (TTL) cannot be decremented by one. All other options are correct. The following changes will be made when the Cisco Express Forwarding (CEF) packet rewrite process occurs:

• The source MAC address is changed to the MAC address of the outbound Layer 3 switch interface.
• The destination MAC address is changed to the MAC address of the next hop routers MAC address
• The Layer 3 IP TTL is decremented by one
• The Layer 3 IP checksum is recalculated
• The Layer 2 frame checksum is recalculated
