Useful info:
1) ip default-gateway   vs   ip default-network   vs ip route 0.0.0.0 0.0.0.0
http://www.cisco.com/c/en/us/support/docs/ip/routing-information-protocol-rip/16448-default.html

2) IP Routing (kinda old info)
http://www.cisco.com/c/en/us/td/docs/ios/12_2/ip/configuration/guide/fipr_c/1cfipadr.html

3) IP CEF
The traffic types are not CEF switched:

• Packets for which there is no entry in the switching cache
  
• Packets destined for the router (icmp, routing protocols)
  
• Broadcast traffic
  
• IP packets with options
  
• Packets that require protocol translation
  
• Encrypted traffic
