  ==================
  LDP CONFIGURATION
  =================
  conf t
  mpls label PRotocol ldp
  ip cef
  
  int
   mpls ip
  
  LDP Verification
  
  show mpls interface
  show mpls ldp discovery
  debug mpls ldp session state-machine
  
  
  =================================
  TRAFFIC ENGINEERING CONFIGURATION
  =================================
  
  conf t
  mpls traffic-eng tunnels
  ip cef
  
  int
   mpls traffic-eng tunnels
   ip rsvp bandwidth 1000
  
  *Dynamic* tunnel config
  
  interface Tunnel X
  ip unnumbered loopback0
  tunnel destination
  tunnel mode mpls traffic-eng
  tunnel mpls traffic-eng autoroute announce
  tunnel mpls traffic-eng priority 7 7
  tunnel mpls traffic-eng bandwidth 100
  tunnel mpls traffic-eng path-option 1 dynamic
  description
  
  *Static* tunnel config
  
  interface Tunnel 6
  ip unnumbered loopback0
  tunnel destination
  tunnel mode mpls traffic-eng
  tunnel mpls traffic-eng path-option 1 eXPlicit name team6exp
  
  From the Router global config, specify the path for the explicit tunnel
  
  ip explicit-path name team6exp enable
  next-address 132.0.0.1
  next-address 134.0.0.1
  next-address 133.0.0.1
  next-address 130.0.0.1
  
  Tunnel Status Verification
  
  Ping tunnel destination address to verify the tunnel is up
  Head end - show int tunnel X accounting
  Midpoint - show mpls forwarding-table
  Both - show mpls traffic-eng tunnels brief
  
  show mpls traffic topology path tunnel X
  
  =================
  QoS CONFIGURATION
  =================
  
  Create a Traffic Class
  
  class-map match-any Router X
  match protocol ip
  
  Create a Traffic Policy
  
  policy-map RxPolice
  class Router X
   police 72000 20000 80000 conform-action set-prec-transmit 2 exceed-action set-prec-transmit 1
  
  Attach Traffic Policy to an Interface
  
  service-policy input RxPolice
  service-policy output RxPolice
  
  QoS Verification
  
  show policy-map interface Serial0/x input/output
  ...
  
  =================
  VPN CONFIGURATION
  =================
  
  PE-PE Routing
  
  conf t
  router bgp 100
   no bgp default ipv4-unicast
   neighbor remote-as 100
   neighbor active
  
  address-family vpnv4

  PE-CE Routing
  
  conf t
  router bgp 100
  address-family ipv4 vrf test1
  neighbor remote-as
  neighbor active
  
  
  CE Routing
  
  conf t
  router bgp
  neighbor remote-as 100
  network mask
  
  The IP Address to be used is the PE routers interface address.
  The network is the loopback address and mask of the CE router
  
  
  Configuring Interfaces (on PE routers only)
  
  conf t
  ip vrf test1
   rd 100:1
   route-target both 100:1
  
  conf t
  int Serial0/X
   ip vrf forwarding test1
  
  
  VPN debug
  
  show mpls for vrf
  show ip bgp vpnv4 all tags
  show ip cef vrf detail
