Configuring a tunnel interface
To configure an MPLS TE tunnel, you must create an MPLS TE tunnel interface and enter tunnel interface
view. All MPLS TE tunnel attributes are configured in tunnel interface view. For more information about
tunnel interfaces, see Layer 3—IP Services Configuration Guide.
Perform this task on the ingress node of the MPLS TE tunnel.
To configure a tunnel interface:
Step Command Remarks
1. Enter system view. system-view N/A
2. Create an MPLS TE tunnel
interface and enter tunnel
interface view.
interface tunnel tunnel-number
mode mpls-te By default, no tunnel interface is
created.
3. Configure an IP address for
the tunnel interface. ip address ip-address { mask-length
| mask } By default, a tunnel interface does
not have an IP address.
4. Specify the tunnel destination
address.
destination ip-address
By default, no tunnel destination
address is specified.
Configuring DS-TE
DS-TE is configurable on any node that an MPLS TE tunnel traverses.
To configure DS-TE:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter MPLS TE view. mpls te N/A
3. (Optional.) Configure the DS-TE
mode as IETF.
ds-te mode ietf
By default, the DS-TE mode is
prestandard.
4. (Optional.) Configure the BC
model of IETF DS-TE as MAM.
ds-te bc-model mam
By default, the BC model of IETF
DS-TE is RDM.
5. Configure a TE class.
ds-te te-class te-class-index
class-type class-type-number
priority pri-number
The default TE classes for IETF mode
are shown in
Table 1 .
In prestandard mode, you cannot
configure TE classes.
