Before you perform the configuration, complete the following tasks:
•
Configure static routing or an IGP protocol to ensure all LSRs are reachable.
•
Configure basic MPLS.
•
Configure basic MPLS TE.
Complete the following tasks to configure an MPLS TE tunnel using a dynamic signaling protocol:
Task
Configuring MPLS TE properties for a link
Configuring CSPF
Configuring OSPF TE
Configuring IS-IS TE
Configuring an MPLS TE explicit path
Configuring MPLS TE tunnel constraints
Establishing an MPLS TE tunnel with CR-LDP
Establishing an MPLS TE tunnel with RSVP-TE
Configuring MPLS TE properties for a link
Step
1.
Enter system view.
2.
Enter interface view of MPLS
TE link.
3.
Configure maximum link
bandwidth.
4.
Configure BC 0 and BC 1 of
the MPLS TE link in the RDM
model of the prestandard
DS-TE.
5.
Configure maximum
reservable bandwidth and
BCs of the MPLS TE link in
the MAM model of the IETF
DS-TE.
6.
Configure the BCs of the
MPLS TE link in the RDM
model of the IETF DS-TE.
Remarks
Optional.
Optional.
Required when CSPF is configured.
Choose one depending on the IGP protocol used.
Optional.
Optional.
Optional.
Use either method.
By default, RSVP-TE is used for establishing an
MPLS TE tunnel.

Optional.
0 by default.
Optional.
0 for both BC 0 and BC 1 by
default.
In RDM model, BC 0 is the
maximum reservable bandwidth
of a link.
Optional.
By default, the maximum
bandwidth, and BC 0 through BC
3 are all 0.
Optional.
0 for BC 0 through BC 3 by
default.
In RDM model, BC 0 is the
maximum reservable bandwidth
of a link.
