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. There are two kinds of LSPs: signaled and static. Signaled LSPs are configured at the ingress LER. When the user enables 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)

Note

Refer to the "Automatic RSVP LSP bring up for MCT" subsection in the "Multi-Chassis Trunking (MCT)" section of the Extreme SLX-OS Layer 2 Switching Configuration Guide for information on auto LSP.
