Static LSP configuration example

Network requirements
Router A, Router B, and Router C all support MPLS.
Establish static LSPs between Router A and Router C, so that subnets 11.1.1.0/24 and 21.1.1.0/24
can access each other over MPLS.

Configuration restrictions and guidelines
•
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 and egress
nodes, but it is not needed on transit nodes. Therefore, you do not need to configure a routing
protocol to ensure IP connectivity among all routers.
Configuration procedure
1. Configure IP addresses for all interfaces, including the loopback interfaces, as shown in
8. (Details not shown.)
2. Configure a static route to the destination address of each LSP:
# On Router A, configure a static route to network 21.1.1.0/24.

Remarks
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.
