To do…

Use the command...

Remarks

Enable the IGP shortcut function

enable traffic-adjustment

Required
Disabled by default

2.

Configure forwarding adjacency

You must create a bi-directional MPLS TE tunnel and enable forwarding adjacency at both ends of the

tunnel to make forwarding adjacency take effect.
Follow these steps to configure forwarding adjacency:

To do…

Use the command...

Remarks

Enter system view

system-view

––

Enter MPLS TE tunnel interface view interface tunnel tunnel-number ––

Enable IGP to advertise the route of
the MPLS TE tunnel to IGP
neighbors.

mpls te igp advertise [ hold-time
value
]

Required
Routes of MPLS TE tunnels are not

advertised to IGP neighbors by

default.

Assign a metric to the MPLS TE
tunnel

mpls te igp metric { absolute |
relative } value

Optional
The metrics of TE tunnels equal the

metrics of their corresponding IGP

routes by default.

Submit current tunnel configuration mpls te commit

Required

Exit to system view

quit

––

Enter OSPF view

ospf [ process-id ]

––

Enable forwarding adjacency

enable traffic-adjustment advertise

Required
Disabled by default

NOTE:

If you use automatic route advertisement, you must specify the destination address of the TE tunnel as the
LSR ID of the peer and advertise the tunnel interface address to IGPs, such as OSPF and ISIS.

Configuring traffic forwarding tuning parameters

In MPLS TE, you can configure traffic forwarding tuning parameters, such as the failed link timer and

flooding thresholds, to change paths that IP or MPLS traffic flows traverse or to define type of traffic that
may travel down a TE tunnel.

Configuration prerequisites

The configurations described in this section are used in conjunction with CSPF and a dynamic signaling

protocol, such as RSVP-TE.
