Command Remarks
3. Configure the
transit node of the
static LSP.
static-lsp transit lsp-name in-label in-label
nexthop next-hop-addr out-label out-label
If you specify a next hop for the
static LSP, make sure the transit
node has an active route to the
specified next hop address.
4. Configure the
egress node of the
static LSP.
static-lsp egress lsp-name in-label in-label
You do not need to configure this
command if the outgoing label
configured on the penultimate hop
of the static LSP is 0 or 3.
Displaying static LSPs
Execute display commands in any view.
Task Command
Display static LSP information. display mpls static-lsp [ lsp-name lsp-name ]
Static LSP configuration example
Network requirements
Switch A, Switch B, and Switch C all support MPLS.
Establish static LSPs between Switch A and Switch C, so that subnets 11.1.1.0 / 24 a n d 21.1.1.0 / 24 c a n
access each other over MPLS.

Configuration considerations
• For an LSP, the outgoing label specified on an LSR must be identical with the incoming label
specified on the downstream LSR.
• LSPs are unidirectional. You must configure an LSP for each direction of the data forwarding path.
• A route to the destination address of the LSP must be available on the ingress node, but it is not
needed on transit and egress nodes. Therefore, you do not need to configure a routing protocol to
ensure IP connectivity among all switches.
