Enabling MPLS TE and RSVP-TE
Context
To create a dynamic MPLS TE tunnel, first enable MPLS TE, enable RSVP-TE globally, enable RSVP-TE on an interface, and perform other configurations, such as setting the link bandwidth attributes and enabling CSPF.
Perform the following configurations on each node of the MPLS TE tunnel.
Procedure
- Run system-view
The system view is displayed.
- Run mpls
The MPLS view is displayed.
- Run mpls te
MPLS TE is enabled on the node globally.
- Run mpls rsvp-te
RSVP-TE is enabled on the node.
- Run quit
The system view is displayed.
- Run interface interface-type interface-number
The MPLS TE interface view is displayed.
- On an Ethernet interface, run undo portswitch
The interface is switched to Layer 3 mode.
By default, an Ethernet interface works in Layer 2 mode.
The mode switching function takes effect when the interface only has attribute configurations (for example, shutdown and description configurations). Alternatively, if configuration information supported by both Layer 2 and Layer 3 interfaces exists (for example, mode lacp and lacp system-id configurations), no configuration that is not supported after the working mode of the interface is switched can exist. If unsupported configurations exist on the interface, delete the configurations first and then run the undo portswitch command.
If many Ethernet interfaces need to be switched to Layer 3 mode, run the undo portswitch batch interface-type { interface-number1 [ to interface-number2 ] } &<1-10> command in the system view to switch these interfaces to Layer 3 mode in batches.
- Run mpls
The MPLS is enabled on the interface.
- Run mpls te
The MPLS TE is enabled on the interface.
- Run mpls rsvp-te
RSVP-TE is enabled on the interface.
- Run commit
The configuration is committed.
