(Optional) Configuring Link Bandwidth
Context
When a non-Huawei device as the ingress node of an MPLS TE tunnel initiates a request for setting up a CR-LSP with bandwidth constraints, configure link bandwidth on the connected Huawei device for negotiation so that the CR-LSP can be set up and network resources are used efficiently.
Perform the following configurations on each node of the MPLS TE tunnel.
Procedure
- Run system-view
The system view is displayed.
- Run interface interface-type interface-number
The MPLS-TE-enabled 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 te bandwidth max-reservable-bandwidth bw-value
The maximum available bandwidth of the link is configured.
By default, the maximum reservable bandwidth of a link is 0 bit/s. The bandwidth allocated to a static CR-LSP built over a link is certainly higher than 0 bit/s. If the maximum reservable bandwidth of the link is not configured, the static CR-LSP cannot be set up due to insufficient bandwidth.
- Run mpls te bandwidth [ bc0 ] bc0-bw-value
The BC bandwidth of the link is configured.
- Run commit
The configuration is committed.
