Configuration prerequisites
Before you configure a static LSP, perform the following tasks:
Identify the ingress node, transit nodes, and egress node of the LSP.
Enable MPLS on all interfaces that participate in MPLS forwarding. For more information, see "Configuring basic MPLS."
Make sure the ingress node has a route to the destination address of the LSP.
If you want to associate the static LSP with an LDP LSP, make sure the egress node of the static LSP has a route to the destination.
