egress node of the
static LSP.

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 1 1.1.1.0/24 and 21.1.1.0/24 can
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.

Remarks
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.
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.
