    MPLS Tunnel Profile Configuration Tasks

    If you anticipate having multiple tunnels to share the same configuration, you can reduce your configuration time by using tunnel profiles to configure your tunnels.

    In the profile, configure the tunnel endpoint last; anything configured after the tunnel endpoint does not take effect until the tunnel is brought up the next time. You can perform all other tasks in any order.

    Note: Tunnel profile configuration tasks are relevant only for traffic engineering networks.

    To configure a tunnel profile:

    1. Create an MPLS tunnel profile and enter Tunnel Profile Configuration mode.
      host1(config)#mpls tunnels profile Lisbon
    2. (Optional) Configure the LSP to announce its endpoint to an IGP.
      host1(config-tunnelprofile)#tunnel mpls autoroute announce isis
    3. (Optional) Specify a tunnel metric to be used by an IGP in its SPF calculation.
      host1(config-tunnelprofile)#tunnel mpls autoroute metric absolute 100
    4. (Optional) Configure the path options used for the tunnel.
      host1(config-tunnelprofile)#tunnel mpls path-option 3 dynamic isis
    5. (Optional) Configure the bandwidth required for the tunnel.
      host1(config-tunnelprofile)#tunnel mpls bandwidth 1240
    6. (Optional) Configure preemption hold or setup priority.
      host1(config-tunnelprofile)#tunnel mpls priority 4 4
    7. (Optional) Configure resource class affinity.
      host1(config-tunnelprofile)#tunnel mpls affinity 0x1100 mask 0xFFFF
    8. (Optional) Configure retry timers options to apply to a specific tunnel to set up an LSP after a route or setup failure.
      host1(config-tunnelprofile)#tunnel mpls no-route retries 100 host1(config-tunnelprofile)#tunnel mpls no-route retry-time 45 host1(config-tunnelprofile)#tunnel mpls retries 250 host1(config-tunnelprofile)#tunnel mpls retry-time 65
    9. (Optional) Associate a text description with the tunnel.
      host1(config-tunnelprofile)#tunnel mpls description southshore
    10. Configure the tunnel endpoint.
      • For static tunnels
        host1(config-tunnelprofile)#tunnel destination

        All tunnels to the specified destination(s) are configured with the profile settings.

      • For dynamic tunnels
        host1(config-tunnelprofile)#tunnel destination isis-level-2 access-list madrid3

    When an endpoint is dynamically learned from the specified routing protocol, MPLS searches its tunnel profiles for a match. The dynamic tunnel is established using the settings from the first matching profile.
