6.
(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
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.
1.
Create the MPLS tunnel interface.
host1(config)# interface tunnel mpls:boston
2.
(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
3.
(Optional) Specify a tunnel metric to be used by an IGP in its SPF calculation.
host1(config-if)# tunnel mpls autoroute metric absolute 100
4.
(Optional) Configure the path options used for the tunnel.
host1(config-if)# tunnel mpls path-option 3 dynamic isis
5.
(Optional) Configure the bandwidth required for the tunnel.
host1(config-if)# tunnel mpls bandwidth 1240
6.
(Optional) Configure preemption hold or setup priority.
host1(config-if)# tunnel mpls traffic-eng priority 4 4
7.
(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.
8.
(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
