Configuring a setup priority and a holding priority for an MPLS TE tunnel
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Enter MPLS TE tunnel interface
view.
interface tunnel tunnel-number
[ mode mpls-te ]
N/A
3.
Configure a setup priority and
a holding priority for the MPLS
TE tunnel.
mpls te priority setup-priority
[ hold-priority ]
By default, the setup priority and
the holding priority are both 7 for
an MPLS TE tunnel.
Configuring an explicit path for an MPLS TE tunnel
An explicit path is a set of nodes. The relationship between any two neighboring nodes on an explicit
path can be either strict or loose.
•
Strict—The two nodes must be directly connected.
•
Loose—The two nodes can have devices in between.
When establishing an MPLS TE tunnel between areas or ASs, you must do the following:
•
Use a loose explicit path.
•
Specify the ABR or ASBR as the next hop of the path.
•
Make sure the tunnel's ingress node and the ABR or ASBR can reach each other.
To configure an explicit path for a MPLS TE tunnel:
Step Command
Remarks
1.
Enter system view.
system-view
N/A
2.
Create an explicit path and
enter its view.
explicit-path path-name
By default, no explicit path exists
on the device.
3.
Enable the explicit path.
undo disable
By default, an explicit path is
enabled.
4.
Add or modify a node in the
explicit path.
nexthop [ index index-number ]
ip-address [ exclude | include
[ loose | strict ] ]
By default, an explicit path does
not include any node.
You can specify the include
keyword to have the CRLSP
traverse the specified node or the
exclude keyword to have the
CRLSP bypass the specified node.
5.
Return to system view.

6.
Enter MPLS TE tunnel interface
view.
interface tunnel tunnel-number
[ mode mpls-te ]
N/A
7.
Configure the MPLS TE tunnel
interface to use the explicit
path, and specify a
preference value for the
explicit path.
mpls te path preference value
explicit-path path-name [ no-cspf ]
By default, MPLS TE uses the
calculated path to establish a
CRLSP.
