1 Static LSPs Configuration
About This Chapter
You can set up a static LSP by manually allocating labels to LSRs. The static LSP is applicable
to stable and small-scale networks.
1.1 Introduction to Static LSPs
The static LSP cannot be set up through a label distribution protocol but can be set up by an
administrator. The static LSP is applicable to a stable and small-scaled network with the simple
topology.
1.2 Static LSPs Features Supported by the S9300
Static LSPs features supported by the system include configuring Static LSPs and Static BFD
for Static LSP.
1.3 Configuring Static LSPs
A static LSP can be set up only after each LSR is manually configured.
1.4 Configuring Static BFD for Static LSP
By configuring static BFD for static LSPs, you can detect connectivity of static LSPs.
1.5 Maintaining Static LSPs
The operations of static LSP maintenance include deleting MPLS statistics, detecting
connectivity or reachability of an LSP, and configuring the trap function on an LDP LSP.
1.6 Configuration Examples
This section provides several configuration examples of static LSPs.

1.1 Introduction to Static LSPs
The static LSP cannot be set up through a label distribution protocol but can be set up by an
administrator. The static LSP is applicable to a stable and small-scaled network with the simple
topology.
Static LSPs cannot be dynamically set up by using the label advertisement protocol, and need
to be manually configured by the administrator. When configuring a static LSP, the administrator
needs to manually allocate labels for each LSR by following the rule that the value of the outgoing
label of the previous node is equal to the value of the incoming label of the next node. Each LSR
on the static LSP cannot sense the changes of other LSRs on the LSP. Therefore, the static LSP
is a local concept.
A static LSP is set up without using label distribution protocols, and does not need to exchange
control packets. Thus, the static LSP consumes few resources and is applicable to small-scale
networks with simple and stable topology. The static LSP cannot vary with the network topology
dynamically. The administrator needs to adjust the static LSP according to the network topology.
1.2 Static LSPs Features Supported by the S9300
Static LSPs features supported by the system include configuring Static LSPs and Static BFD
for Static LSP.
Static LSPs
Static LSPs need to be configured manually by the administrator. Each LSR on the static LSP
cannot sense the status of the entire LSP, because the static LSP is a local concept. A static LSP
cannot vary with the change of a route dynamically. The administrator then needs to adjust the
static LSP.
Static BFD for Static LSPs
The S9300 supports static BFD for static LSPs. BFD is a bidirectional detection mechanism.
When static BFD is applied to static LSPs which are unidirectional, the reverse links can be
either IP links or static LSPs.
1.3 Configuring Static LSPs
A static LSP can be set up only after each LSR is manually configured.
1.3.1 Establishing the Configuration Task
Before configuring a static LSP, familiarize yourself with the applicable environment, complete
the pre-configuration tasks, and obtain the required data. This can help you rapidly and correctly
finish the configuration task.
Applicable Environment
A static LSP works normally only after all the LSRs along the LSP are configured.

The setup of static LSPs does not require the label distribution protocol or exchange any control
packet. Thus, the static LSPs consume little resources and are applicable to small-scale networks
with simple and stable topology. The static LSPs cannot vary with the network topology
dynamically. The administrator, therefore, needs to adjust the static LSPs according to the
network topology.
Static LSPs and static CR-LSPs share the same label space (16 - 1023).
Static LSPs are used over the MPLS L2VPN.
For information about the MPLS L2VPN configuration, refer to the Quidway S9300 Terabit
Routing Switch Configuration Guide - VPN.

If the configurations succeed, run the preceding commands, and you can view as follows:
lWhen the display mpls static-lsp command, information about the static LSP
configuration is displayed, including the name of the static LSP, FEC, values of the
incoming label and the outgoing label, and the incoming and outgoing interfaces. In
addition, you can view that the status of the LSP is Up.

----End
1.4.3 Configuring BFD with Specific Parameters on Ingress
To detect a static LSP through a static BFD session, you need to configure BFD parameters on
the ingress node of the static LSP.
Context
Do as follows on the ingress of the static LSP:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
bfd cfg-name bind static-lsp lsp-name
The BFD session is bound to the static LSP.
Step 3 Configure the discriminators.
lRun:
discriminator local discr-value
The local discriminator is configured.
lOr, run:
discriminator remote discr-value
The remote discriminator is configured.
Step 4 (Optional) Run the following commands to adjust the minimum interval for the local device to
send BFD packets, the minimum interval for receiving BFD packets and the local BFD detection
multiple:
1. Run the quit command to return to the system view.
2. Run the mpls command to globally enable MPLS and the enter the MPLS view.
3. Run the mpls bfd min-tx-interval interval command to adjust the minimum interval for
the local device to send BFD packets.
The minimum interval for the local device to send BFD packets is set.
When the device is equipped with an FSU, by default, the value is 10 milliseconds;
otherwise, by default, the value is 1000 milliseconds.
If the backward link is an IP link, this parameter is not applicable.
Actual interval for the local device to send BFD packets = MAX { Locally configured
interval for sending BFD packets, Remotely configured interval for receiving BFD
packets}; Actual interval for the local to receive BFD packets = MAX {Remotely
configured interval for sending BFD packets, Locally configured interval for receiving
BFD packets}; Local detection period = Actual interval for the local device to Receive BFD
packets x Remotely configured BFD detection multiple.
