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.

Create an MPLS tunnel profile and enter Tunnel Profile Configuration mode.


                  
                     host1(config)#mpls tunnels profile Lisbon

(Optional) Configure the LSP to announce its endpoint to an IGP.


                  
                     host1(config-tunnelprofile)#tunnel mpls autoroute
                           announce isis

(Optional) Specify a tunnel metric to be used by an IGP in its SPF calculation.


                  
                     host1(config-tunnelprofile)#tunnel mpls autoroute
                           metric absolute 100

(Optional) Configure the path options used for the tunnel.


                  
                     host1(config-tunnelprofile)#tunnel mpls path-option
                           3 dynamic isis

(Optional) Configure the bandwidth required for the tunnel.


                  
                     host1(config-tunnelprofile)#tunnel mpls bandwidth
                           1240

(Optional) Configure preemption hold or setup priority.


                  
                     host1(config-tunnelprofile)#tunnel mpls priority
                           4 4

(Optional) Configure resource class affinity..


                  
                     host1(config-tunnelprofile)#tunnel mpls affinity
                           0x1100 mask 0xFFFF

(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

(Optional) Associate a text description with the tunnel.


                  
                     host1(config-tunnelprofile)#tunnel mpls description
                           southshore

Configure the tunnel endpoint.

For static tunnels
host1(config-tunnelprofile)#tunnel destination 10.1.2.5 10.1.2.6

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.
