MPLS Tunnel Configuration Tasks

Complete the following tasks to configure a tunnel interface. 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 configuration tasks are relevant only for traffic engineering networks.

MPLS Tunnel Configuration Tasks
(Optional) Configure an administrative weight for the interface that overrides
the weight assigned by the IGP.
host1(config-if)#mpls traffic-eng administrative-weight 25
Create the MPLS tunnel interface.
host1(config)#interface tunnel mpls:boston
(Optional) Configure the LSP to announce its endpoint to an IGP (sometimes
referred to as registering the endpoint).
host1(config-if)#tunnel mpls autoroute announce isis
(Optional) Specify a tunnel metric to be used by an IGP in its SPF calculation.
host1(config-if)#tunnel mpls autoroute metric absolute 100
(Optional) Configure the path options used for the tunnel.
host1(config-if)#tunnel mpls path-option 3 dynamic isis
(Optional) Configure the bandwidth required for the tunnel.
host1(config-if)#tunnel mpls bandwidth 1240
(Optional) Configure preemption hold or setup priority.
host1(config-if)#tunnel mpls traffic-eng priority 4 4
(Optional) Configure resource class affinity.
host1(config-if)#tunnel mpls traffic-eng affinity 0x000C3000 0xFFFFFFFC
This example of a masked affinity matches only links configured with attribute
flags from 0x000C3000 to 0x000C3003.
(Optional) Configure retry timer options to apply to a specific tunnel to set up
an LSP after a route or setup failure.
host1(config-if)#tunnel mpls no-route retries 100
host1(config-if)#tunnel mpls no-route retry-time 45
host1(config-if)#tunnel mpls retries 250
host1(config-if)#tunnel mpls retry-time 65
