Setting up signaled LSPs
An LSP consists of an actual path of MPLS routers through a network, as well as the characteristics of the path, including bandwidth allocations and routing metrics.
Signaled LSPs are configured at the ingress LER. When you enable a signaled LSP, RSVP causes resources to be allocated on the other routers in the LSP.
Configuring a signaled LSP consists of the following tasks:
- Specifying a path for the LSP to follow (optional)
- Setting parameters for the signaled LSP
- Specifying which packets are to be forwarded along the LSP (optional)
