In cisco's manual "Configuring Multiprotocol Label Switching" I found the following set of configuration commands under the headings
 
1. Configuring MPLS Traffic Engineering Paths
Router(config)# interface tunnel 2003
Router(config-if)# ip unnumbered e0/1 
Router(config-if)# tunnel mode tag-switching 
Router(config-if)# tunnel tsp-hop 1 10.10.0.103
Router(config-if)# tunnel tsp-hop 2 10.11.0.105
Router(config-if)# tunnel tsp-hop 3 10.12.0.108
Router(config-if)# tunnel tsp-hop 4 10.13.0.110 lasthop
Router(config-if)# exit
 
2.Configuring an MPLS Traffic Engineering Tunnel
configure terminal
interface tunnel1
  ip unnumbered loopback 0
  tunnel destination 17.17.17.17
  tunnel mode mpls traffic-eng
  tunnel mpls traffic-eng autoroute announce
  tunnel mpls traffic-eng bandwidth 100
  tunnel mpls traffic-eng priority 1 1
  tunnel mpls traffic-eng path-option 1 dynamic
 
now create the path called 1
configure terminal
ip explicit-path identifier 1
 next-address 131.0.0.1 
 next-address 135.0.0.1 
 next-address 136.0.0.1 
 next-address 133.0.0.1 
 
what is the difference between traffic engineering tunnel and Traffic engineering path ?
